Running Google Talk on ubuntu

[Giorgos]

The only reason I keep booting into windows is to use the voice chat
feature of google talk. It doesn't work with wine atm and I can connect
to google talk's servers with gaim but you have to have the official
client to use the voice chat.

This functionality is vital to me, I have installed skype but it gives
me problems (laggy in both windows and linux versions.)
