Oh it is totally doable... but there are so many factors.
1. A person in the US with the willingness, Sunday Ticket, high speed connection, cables, TV card, PC, Slingbox, etc etc etc
2. A person with necessary high speed internet connection in the UK. Most broadband in the UK comes at 2meg maximum - higher than that requires som eserious outlay.
3. A location to show the games. I would do it at my flat, but more than 7 people we run out of seats, more than 10 people we run out of viewing space and more than that there's no room to move.
I dunno - it is doable - but on what scale I don't know.
