Hi Bill,
I am Jon Parrott, and I'm the project manager for PhoenixGL. The project is currently on hiatus due to my housing situation. However, you can expect me to start working on it again as soon as I find a suitable home. I'm excited to hear that you want to use our library for a game, and I'll be willing to help in any way I can. Drop me an email with any questions you have and I'll do my best to answer them as quickly as possible. As far as feature requests, I'll keep them in mind but I don't have a system to develop on at the moment. However you'll notice it's very easy to modify the engine, and if you wanna add features please feel free. If you'd like to contribute back to phoenix, email me any sources and I'll gladly add them to the SVN.
With kindness,
Jon.
