Exactly. And unless the game has some in-game check on running it on multiple computers at the same time (like BFBC2, which will boot off one player from being logged into the game if it's running in two places and logged in with the same account - this kind of thing pretty much happens only in games with log-in features), you can run it for LAN or whatever. My roommate, brother, and some friends all like to LAN up Sins of a Solar Empire. Impulse doesn't even need to run.
Only disadvantage is that you need Impulse for patches for all games published by Stardock, but that's not too much of a problem. And the games store is smaller than Steam's, but it's pretty decent nonetheless.
