This sounds like an awesome idea, some things to take into consideration would be distance filters, I know Second Life has these.
The further you are, the more quiet the speaker is. That would reduce too many people speaking in one go.
Also, blocking people. You only need to be on voice chat for 5 minutes on any game to hear how people abuse the chat at times.
Apart from that, this sounds like an excellent idea for things like Clan wars, Dungeoneering, or just general chitchat.
Gets my approval.
