Fiber to the home and other such types of high bandwidth connections should compensate for the overhead incurred by an encrypted network overlay which would allow me to run all the BT I want ... even over Comcast's network. Granted there is nothing concrete in this area quite yet, but then again ISP's don't have concrete filtering systems quite yet either.
