Methods for performing client-hosted application sessions in distributed processing systems

In a client computer included in a distributed processing system, a method whereby the client computer is admitted to an application session hosted by a host client included in the distributed processing system and the client computer obtains current application data regardless of transmission latency associated with the application data, the method comprising the steps of:

• initiating transmission of data to the host client, the data representing a request for admission into the application session;
• after being admitted to the session in response to the request such that the client computer becomes an application client, but prior to completely receiving the application data from the host client, performing the steps of
• receiving at least one state update packet forwarded directly to the client computer from at least one of one or more other application clients, the one or more other application clients including the host client and any other client that is included in the distributed processing system and is participating in the application session;
• and
• compiling pending queue data at the client computer based on the at least one state update packet;
• receiving the application data from the host client, the application data enabling the client computer to participate in the application session;
• and
• updating the application data using the pending queue data.
