gaming voice chat mac vs. pc

Teamspeak doesn't have a mac version yet (they say one is coming soon) but I know Roger Wilco has a BETA version that people says works for pc - mac chatting:

I've used this back in the day - pretty much the same shit as teamspeak - prolly not as good, but might be our only option. Same kinda situation - you make a private room, we all join in, and then we fire up whatever game. I don't have a mic anderson yet, but will get one this weekend 4 sure.
