If Houtz sends the money to me in Tennessee and I pay for it, he'd only be blacked out from Cardinals and Reds games I would assume, right? Or do they determine the blackout from your IP address. If it works by your IP address or something where they can determine where you are, then you are definitely blocked from all Pirates games if you live in PA, and most likely if you live in one of the surrounding states of PA. There's a blackout chart on mlb.tv.
I had it last year, but never ran into this problem as the Nats and Yankees are no where near Memphis.
It's definitely an awesome thing though, even if you can't see your own team. It's always good to come home and be able to watch some baseball whenever you want.
