playing games off PC HD or DVD ROM

[arriej44]

Okay, I read on the X-Box Media Player homepage that the newest version can play DivX movies that or located on a networked PC's HD. So my question is, if we can do that, do you think we're far off from being able to play a game off the networked PC's HD? Or even better, why not off the PC's DVD or CD-ROM? That would allow you to use any media your CD-ROM can read. Anyone have any insight on why this can or can't work? Thanks!
