Microsoft Instant Messaging clients have the ability to invite Instant Messaging contacts to start a Microsoft NetMeeting session. This is possible because NetMeeting is a Microsoft DirectPlay application that is registered in the local computer's registry. Instant Messaging references all DirectPlay applications and exposes them for invitation to other contacts. Full DirectPlay application functionality between Instant Messaging clients is contingent upon the specific application.
The DirectPlay application programming interface (API) for Microsoft Windows lets developers create multiplayer games, game servers, chat clients, and other network applications without writing code for individual transports, protocols, or online services.
