Do carrier ISPs classify their voice traffic as Really Important, and everybody else's data as Best Effort? This isn't just selfishness, since We All Know voice is less tolerant of latency and jitter than TCP.

We do? Try to keep a single-TCP-stream session over 500 mbit/sec of goodput halfway across the country sometime. Most of us who have VoIP boxes have 20ms or better jitter playout buffers. Ever (successfully) talk to someone over a GSM handset when their coverage was a little marginal? The human ear is a marvelous tool compared to a TCP timer.
