Two options for getting around the MLB local area blackout regulations. Both require the MLB.tv subscription, which is $25 / month for high def. (BTW, if you haven't tried MLB.tv, it's really a great product. Many PS3/BlueRay type players have an app for it, too)
1) MLB.tv experimented with a local area only package here in San Diego last year. $20 / mo for just the Padres. 2) Rather than that, I simply used one of my VPS' in another region to create an SSH tunnel through which to route the MLB.tv signal. They use your IP, not your billing address, to determine access.
