As Microsoft says, DirectPlay8 is deprecated. It is a sad news to some developers(including me!) who adopts DirectPlay8 for their project for a long time. Thus... I have a plan to begin an open source project for a game networking engine which is very similar to DirectPlay8, of course, well-proved even by several commercial projects. As we don't hurry for source code debugging for now, the time for needs for source code will come sooner or later, considering the nature of network game development. And there's more reasons for this project: * We may expect the mimic version of DirectPlay8 can have more features than original DirectPlay8 provided by Microsoft. * Visible source code enables reliability. * Collective ownership encourages developers to contribute more updates. However........... As many open source project experienced, an open source may grow up very slowly or even may be deprecated unless there's many contributors. So, please let me know your interest or willing to contribution by replying to this thread. Thanks. Bae,Hyun-jik

Just adopt RakNet or similar libraries. Spawning yet another OS network lib isn't just pointless. Think of it how many OS projects there are that do the same. A bunch of graphics wrappers, a dozen network libraries, a bunch of OS Linux graphical shell, etc.

If you want to write code for some OS project, join an existing community.

RakNet or OpenTNL are both free, open, readily available, tested libraries that do most of the things DirectPlay does. I suggest you start out by looking at one of those packages. The Forum FAQ has a longer list of available packages.
