I think that you'd be better off trying to shape your traffic.  You can
present the option that while you won't be blocking the "bad" traffic,
you'll be better able to guarantee service levels to appropriate use of the
network.  You can have one level of shaping during the day and another for
the evening.

In the recent weeks I have found that the newer versions of the most popular
p2p file sharing apps have begun port hopping (moving from 1214 to 80 etc).
I was wondering if anyone out there knew of a listing of the "router"
machines...i.e. router.limewire.com, for each service. I am considering
blackholing them over going through and blocking all these ports manually. I
know the question everyone is begging to ask is "why not just block
everything and open up only what you need". There are political measures
that keep me from doing that. Anyways, any help would be appreciated.
