VoIP - Voice Chat for WoW

The word on the street says voice chat will be implemented in an upcoming patch. This is good news for the alliance, as I see this helping them in BGs more than the already organized Horde players. I'm wondering what options, if any, will we have with the new voice chat system.

The first thing that comes to mind is people not wanting to use it because their IRL voice might not be representative of their in-game persona, or their voice just doesn't command the same amount of respect. That Tauren tank you would have never thought to second guess just turned out to be a prepubescent, and while this shouldn't change your association with the said Tauren, sometimes it's hard to avoid.

I'd like to see an option to disguise ones voice in different tones. The tones would have to be realistic or they would be abused - I for one would pick an alien voice over my own any day! I believe a voice disguiser would allow minors & women a comfortable feel in the world of voice chat. This way their judgment would be on their play-style and not the sound of their voice.

Some other nice-to-have options might include a mute option for that person who continuously curses, a parental control for non-voice chat with people not on a friends / approved list of players. I would also like to see various broadcast options, such as party, raid, & guild so that you can broadcast different messages to different groups without leaving / entering a different channel.

These are just some ideas for the implementation of voice chat; can anyone else think of some other options they'd like to see with the new voice chat?
