I doubt Valve would make steam open source. A port to linux would make sense if it made running game servers easier. I doubt it will make many games get dedicated ports to linux though.

Just because Steam works on Linux though doesn't mean all the games would...

Yes, but the rumour is that the Source engine is also to be ported.

Oh Lord

Oh God

Really? REALLY?

I can finally switch back to Ubuntu without hesitation? Oh thank you, mighty Valve, for this blessing you have bestowed upon me

Its good news... but we'll see how many games bother to support Linux. Steam on its own is useless.

Pity Steam isn't in my good books at the moment :P

steam and many games purchased off steam work on Linux already, under wine.

getting native Linux support would be a huge bonus, however
