Agreed.  AFAIK P2P applications don't violate anybody's contract terms. 
  Using P2P to distribute or (arguably) download copyrighted materials 
without the copyright holders permission probably does.  But randomly 
killing P2P connections penalizes the legitimate users just as much as 
the illegitimate ones.

And the protocol documents (RFCs 791 & 793) specify what these packet 
headers and bits are for, and Comcast is in violation of those 
protocols.  This is just as much an abuse of the system as email spam, 
SYN floods, and other attempts to either break the Internet altogether 
or subvert it to purposes at variance with the interests of the vast 
majority of users (both commercial and individual).
