Is there documentation describing the client/server protocol used for the RIO audio receiver? That would let me rewrite the server (and better understand what is done on the client and what is done on the server).

With this documentation I could write my own server, and fix some of my problems.

Thanks.

There's a FAQ entry on this topic here. Also, if you're into digging through source code, a lot could be gleaned from an examination of the code to these.
