[Openal] OpenAL with C++ WindowsForm application?

[Reese]

If your interested I've been working on an object oriented wrapper that is
very close to being ready for its first release, it's written in c# and
comes with unit tests and some samples. I'm currently finishing up streaming
but most of the other features are there, if nothing else it might provide a
good place to start. My goal is to recruit people to use it in a game soon
and write some articles on how to use it. If you use it let me know what you
think. http://openal-net-sdk.sourceforge.net
