Besides, it would seem that whatever games are made available for steambox would be binary compatible with other Linux distributions anyway (and software for other Linux distros should run on steambox) unless they do something really crazy with it.
For me the distinction is, can I play the game on my computer running my distro of choice, or can I only play it on the Steambox, which happens to be running Linux.

I have seen nothing that would indicate this one way or the other.
Regards distros, they don't seem to mind people repackaging for other distros though it would be unrealistic to expect support for running the games under every conceivable distro of which there are thousands.
