storing the downloaded content at a location, wherein the location is only accessible via the special purpose virtual machine; and streaming the stored content over a virtual network to a general purpose virtual machine, wherein the special purpose virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the content to be downloaded may be received from one or more of a remote media server, the Internet and a local area network (LAN). ### Claim 2 A method comprising: downloading content to a special purpose virtual machine; storing the downloaded content at a location, wherein the location is only accessible via the special purpose virtual machine; and streaming the stored content over a virtual network to a general purpose virtual machine, wherein the special purpose virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the content is media content. ### Claim 3 A method comprising: downloading content to a special purpose virtual machine; storing the downloaded content at a location, wherein the location is only accessible via the special purpose virtual machine; and streaming the stored content over a virtual network to a general purpose virtual machine, wherein the special purpose virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein streaming the stored content over a virtual network to a general purpose virtual machine includes streaming the stored content over the virtual network to an application running on the general purpose virtual machine, wherein the streamed content is only accessible via the application. ### Claim 4 (depends on 3) The method of claim 3, wherein the application allows a user to view the content. ### Claim 5 A method comprising: downloading content to a special purpose virtual machine; storing the downloaded content at a location, wherein the location is only accessible via the special purpose virtual machine; and streaming the stored content over a virtual network to a general purpose virtual machine, wherein the special purpose virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the location is a virtual disk partition that exists on the same PC as the special purpose virtual machine and the general purpose virtual machine. ### Claim 6 (depends on 5) The method of claim 5, wherein stored content on the virtual disk partition is encrypted and can only be decrypted via a mechanism known only to the special purpose virtual machine. ### Claim 7 (depends on 5) The method of claim 5, wherein stored content on the virtual disk partition is protected by a disk hardware security mechanism. ### Claim 8 A system comprising: a closed virtual machine; and a general purpose virtual machine, wherein the closed virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the closed virtual machine comprises a download manager and a server, the download manager to download content and to store the downloaded content at a location, wherein the location is only accessible via the closed virtual machine, and the server to stream the stored content over a virtual network to the general purpose virtual machine, wherein the content to be downloaded may be received from one or more of a remote media server, the Internet and a local area network (LAN). ### Claim 9 A system comprising: a closed virtual machine; and a general purpose virtual machine, wherein the closed virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the closed virtual machine comprises a download manager and a server, the download manager to download content and to store the downloaded content at a location, wherein the location is only accessible via the closed virtual machine, and the server to stream the stored content over a virtual network to the general purpose virtual machine, wherein the content is media content. ### Claim 10 A system comprising: a closed virtual machine; and a general purpose virtual machine, wherein the closed virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the closed virtual machine comprises a download manager and a server, the download manager to download content and to store the downloaded content at a location, wherein the location is only accessible via the closed virtual machine, and the server to stream the stored content over a virtual network to the general purpose virtual machine, wherein the server to stream the stored content over a virtual network to an application running on the general purpose machine, wherein the streamed content is only accessible via the application. ### Claim 11 (depends on 10) The system of claim 10, wherein the application allows a user to view the content. ### Claim 12 A system comprising: a closed virtual machine; and a general purpose virtual machine, wherein the closed virtual machine and the general purpose virtual machine exist on the same personal computer (PC), wherein the closed virtual machine comprises a download manager and a server, the download manager to download content and to store the downloaded content at a location, wherein the location is only accessible via the closed virtual machine, and the server to stream the stored content over a virtual network to the general purpose virtual machine, wherein the location is a virtual disk partition that exists on the same PC as the closed virtual machine and the general purpose virtual machine. ### Claim 13 (depends on 12) The system of claim 12, wherein stored content on the virtual disk partition is encrypted and can only be decrypted via a mechanism known only to the closed virtual machine. ### Claim 14 (depends on 12) The system of claim 12, wherein stored content on the virtual disk partition is protected by a disk hardware security mechanism. ### Claim 15 A computer-readable storage medium containing instructions which, when executed by a processing system, cause the processing system to perform a method, the method comprising: downloading content to a special purpose virtual machine;
