Well, do they do RTP over UDP or TCP? TCP worked easily on my stock G1, but similar UDP code did not. Granted I didn't try very long because the way I'm using it, I can easily switch to UDP when/if I get it to work. I'd be interested in a proper UDP solution.

Other than that, you'll have scaling issues using a single machine regardless.
