1 xp mce2005 and 2 xbox360's? Possable

Have one Xbox360 hooked up to the Media Center PC. This setup works so well, I want to add a second Xbox360 for the bedroom.

Is is possable to use 2 360's with one XP MCE 2005 PC?

Thanks

Excellent I purchased a premimum 360 system today, and wanted to be sure before opening it.

I wonder if the 360 supports gigabit lan?

Thanks for the fast response.
