My parents own a slingbox that I have access to and that my siblings on the west coast use to watch philly sports. It's a $200 flat rate which isn't the most cost-effective thing in the world, and you would need to hook it up to someone who does have cable, but I thought I'd just share. It's also non-perfect (you generally have to watch on a 30 second delay if you don't want it to be tiltingly jumpy), but it has come in handy a lot.
