Concerning latency
Well the bingo latency number used a lot in voice is
50ms. Im simplifing without getting into all the details, but that's an
important number. As far as VoIP goes, I think higher latency is ok, it's
more important to have "consistent"

Some thoughts:
- Coast-to-coast "guaranteed latency" seems too low in most cases that I've
seen. Not calling CEOs and marketers liars but the real world doesn't seem to do
