Network end users to pull down 2 gigabytes a day, continuously?

Ah-ha. You are mistaken. :-)

My focus is next-gen broadband and video. The wifi guys have their  
own department.

Good try, though. :-)

Personally, I am against the peer-to-peer method for business  
reasons, not technical ones. It will be difficult to get blessed by  
the content providers and painful to support (high opex).

I have confidence in creative engineers. I am sure any one of us  
could come up with a workable solution for P2P given the time and  
proper motivation.

All in all, P2P is really limited to a VoD model. It is hard to say  
whether or not VoD would ever become such an important service over  
the Internet, as to press content providers into an agreeable nature.
