Region-free games and Live

So, I'm thinking about importing Ghostbusters for my 360, since it's not released here until October thanks to Sony's exclusivity deal.

Many websites, including Kotaku, note that the US version of the game is region-free, as I believe quite a few 360 games are. My question is though, if I import the game and play it, am I risking an Xbox Live ban or anything like that? I know it sounds like a stupid question, but I'm not really well-versed with Live policy. It's a legitimate purchase from an online retailer, so the publisher and MS are still getting their money.

I'm vehemently opposed to game piracy and shady dealing, so I really wouldn't want to be banned for playing a legit game in the wrong region. What's the skinny?Region-free games and Live
