I'm currently programming a 3D game engine which is primarily focused on DirectX and windows operating systems, though support for other systems will later be added(not to concerned with it right now). For the networking, I've written my networking library using sockets (as the DX10 documentation recommends) instead of DirectPlay. However I would really like to include something similar to DirectPlay's voice features(avialibe in the DirectPlay 8 version) into my engine to allow games written with my engine to support voice chat amongst players. Does anyone have any suggestions on how I can implement this feature?
