Yup
I know from here that most of the people i know (adults that pay for the broadband) that they are not in it for P2P but for business, news, radio, entertainment, games, email etc etc. Alot of kids are in it for P2P but they would not stop using the internet (that their parents payed for) if it went away.
Peronally i dont give a toss about P2P, not that i never use it but i could manage well without, and i would sertainly not cancel my broadband if it went away.
