Soooo...anyone know how this works?  I was looking at the mlb.com site, and I see a lot of the phrase "local blackouts," which seems to defeat the purpose.  Is that for listening to the game over the computer? (Can you not watch the game on the computer? Or is that more than $15/season, I assume.)  Is that a local setup only (i.e., for one computer), or can I access that from any computer with internet access (say, via a user name and password)?

Also, how is GameDay audio related (if it is at all) to mlb.com At Bat for the iPhone, which is also for $15? If you upgrade from an iPod Touch to an iPhone, do you have to pay for all your paid apps all over again?

Anyone have a clue on this stuff?
