I personally wouldn't be able to take advantage of this, since I'm retired and don't go to school, but I think this game is good enough that it'd be great to stick on a USB key and take down to the computer lab or to play on your lunch hour. Old school classics like Quake 3, Counter Strike, and Unreal Tournament were made portable by their communities because they were so damn good people couldn't wait to get home in order to play. Now, this might be handing over the keys to the pirate crowd, but it also might be one of those "swing vote" issues for pirates that makes them say "these devs are so cool, let me give them their $15". I don't think I've ever seen a game come out of the gate with a portable install option, created by the devs themselves. This wouldn't be a deal-breaker if it didn't happen, but I think it'd be something to put on the feature list of the steam page, and it would convince more than a few folks to hand over some cash.
