From what I've read the new version of teamspeak is due this quarter. What this means is that chat will be viable from the web page but were not sure about voip as of yet but since it's written to fit the dot net platform & will have an SDK I can pull any data I want from the new version so I wouldn't reccomend any changes right now.
Other then that we need to implent the cosmetic and functional changes before we do any other work & as you know were waiting for feedback from our constituants from within other communities in which appears to be moving pretty slowly...
