Choosing a new ISP *might*, assuming you can get a new ISP where
you live (I'm fortunate enough to have iProvo, otherwise Comcast
would be my only available option: Qwest doesn't have DSL service
in my neighborhood).  There's always the possibility, though,
that a new ISP would be just as bad.

Running all your P2P traffic over a VPN *might* also fix the
problem.  (In Comcast's case, I'm fairly sure it will, but
there's nothing that prevents them from degrading VPN traffic
in the future, too.)  Relakks.com is one VPN option that might
be worth a look, if you plan on running much torrent traffic
on your Comcast connection.  Be careful about going over the
"nonexistent" Comcast usage limits, though, or you may end up
with no ISP at all.

A new protocol over UDP definitely won't fix the problem, though.
It's no harder to block than the old one.
