Distributed computing services platform

A computer program product for use in a network that includes a plurality of servers that communicate with a plurality of client devices including a first client device and a second client device, the computer program product for implementing a method for facilitating a mid-session transition between the first client device and the second client device, the computer program product comprising a physical computer-readable storage medium having stored thereon the following:

• computer-executable instructions for detecting the receipt of state information stored on at least one server;
• computer-executable instructions for causing interaction in a session with the first client device;
• computer-executable instructions for causing the state information to be updated in response to interaction in the session with the first client device;
• computer-executable instructions for causing the updated information to be stored on the at least one server, wherein the state information is stored on the at least one server utilizing a data structure that follows a schema recognized by the plurality of servers and the first and second client devices, wherein the meaning of the state information is implied by the schema;
• computer-executable instructions for detecting the receipt of the updated state information when the session is continued on the second client device;
• and computer-executable instructions for causing interaction in the continued session with the second client device based on the updated state information,
• wherein the plurality of servers comprises a server federation, wherein the acts of retrieving state information, interacting in a session with the first client device, storing the updated information, retrieving the updated state information, and interacting in the continued session are cooperatively performed by two or more servers of the server federation.
