Voice in SecondLife?

Voice in SecondLife?
Well, as seen in the Linden Blog at http://blog.secondlife.com/2007/02/27/bringing-voice-to-second-life/, seems that a voice chat system will be being built into the SL client. I myself have a few questions about this:
Will this inclusion complicate the open sourcecode model that Linden Lab has chosen for itself?What effect will this have on the fact that a significant percentage of SL residents have cross-gender avatars?
Will we start to see 'voice discrimination' in SecondLife?
The last needs a bit of explanation: What I mean is, will the sound of people's voices cause people to categorize them? The idea of a man playing a female is one version of this, but what about people with voices that don't carry into 'character'? A huge robot warrior that sounds like a perky young woman just does not bring forward the same image as it did when just using text chat.
Also, what about those who choose NOT to use voice? Will they be discriminated against as well? Will we begin to see clubs that say "Voice Only", or even "Text Only"?
Do we really care?
Not really. The fact is, none of it matters. It's a new technology. If you don't want to use it, nobody can make you. If a club tried to say "X Only", I can PROMISE you that they will only be hurting themselves, since the other side will just take their money elsewhere. People who claim "You don't voice! You must have something to hide!" will suddenly find themselves outed as a bigot.
So, my opinion? Just let it happen, and use it or ignore it as you like. It's really not anything more than another step in the evolution of SL.
And for the record, I would NEVER use anything other than voice for long technical explanations. I script, you see, and do quite enough technical writing as it is. I'm lazy that way.
