Dave,
Well, once again "there ain't no such thing as a free lunch."
Anyone who thinks they can get "free" telephony (or video or P2P) over
the internet will be in for a rude awakening.
The ISP "all you can eat" end-user pricing models are, of course, based
on some set of assumptions about typical usage.
If you add significant VoIP/video/P2P the model gets broken -- either
quality levels go down, or the ISPs go broke adding more equipment.
Rather than get crushed under a flood of P2P packets, ISPs will
eventually have to raise prices or protect themselves (P-Cube,
www.caspiannetworks.com, etc.).
QOS is not necessarily meant to cut back any class of traffic; but QOS
does ALLOW systems to prioritize traffic, and develop appropriate
pricing models. In the future, we should expect that ISPs will offer
higher levels of QOS tied to higher charges. You will be able to pay
for high-quality VoIP or video, if that's important to you. (Remember
why student standby tickets used to be so cheap -- you could get
delayed!)
Remember, anyone who expects a free lunch usually gets a pretty crummy
lunch.
