> I'm not up to speed on Bittorrent, but are they specifically blocking Bittorrent, or is coming under the ruberic of "thou shall not run a server behind your cable modem"?
Maybe try googling before you comment? Comcast would inject forged TCP rst packets to inbound bittorrent connections. It did not send these packets to people running servers or other peer-to-peer protocols. In fact, people complained that the resets would sometimes prevent Windows Remote Desktop from working and Comcast adjusted their system to prevent it from jamming.

> I'm interested to know what other sorts of things/applications ISPs may be blocking. Is there a name-and-shame site out there listing various ISPs and what they don't allow.
The current issue isn't really blocking, it's throttling. There are a couple of sites that do this sort of measurements. Look at http://www.measurementlab.net/
> Is it 10% of the population who can't get DSL, wireless, satellite or some other form of competition of some kind?
The FCC's current definition of broadband is 25mbps.
Vast majority of DSL isn't broadband speed (Avg is 10Mbps.) 4g isn't broadband speed (~12Mbps). Satellite isn't broadband speed (~15Mbps and usually expensive compared to wired.)
At 25mbps, 20% have no service and 55% have only one service.
