Because we don't complain about net latency enough.
One of the beautiful aspects about Bancho is how small the bandwidth footprint on it is. As optional as it would be, you're still enabling those with faster connections/more bandwidth to alienate those with less. Unless there was a per-user opt-out (versus the Room Master controlling it) I'd have to be strongly against it.
I can sympathize with the reason for suggesting it, though. Unlike almost every other "this application already does what you want" feature request, managing voip using something like vent/skype is enough overhead to make it too inconvenient to be worthwhile.
