MapleStory on Steam?

Since people are still asking, DFO does patch normally but in a Steam window. I would assume that you'd see the same Maple patcher, but with Steam's black/gray striped window border.

Anyway, I'd love Steam to have MapleStory. I don't see what harm it could do. There are tons of crappy games on Steam already. Heck, MapleStory isn't even that crappy anymore thanks to new-and-improved Nexon.
