Ok Patrick, you're right. But with the popularity it has achieved, I
don't think blocking is a solution. Maybe a combination of local caching
with some policing could be. If the statistics I've seen so far are
right, then the caching works wonders. Imagine what that could be for
your users! 

I guess that if you block (specially for residential users) they will
flee to some other provider. Also blocking affects P2P as a system...
(which I like, but that's a personal opinion ;-)

Pablo.

I do agree but maybe many of your customers are
suffering because a limited number of them are
aggressively consuming YOUR bandwidth (lets consider
it is not unlimited)by starting large number of
concurrent connections. 
That why Allot is also proposing a different approach
to control P2P: fairness per users (and not per
connections. No limitation - no application control -
just equity per user when your bandwidth is congested.

If you are concerned by doing "any effort to improve
users experience" it could be a good complement !!
