To have your Xbox360 wake up your mediacenter automatically when you start the mce extender. You have to have the option "Wake on Ping" in your network card driver set to enabled.
Has anybody tried this on Vista? I'm currently running RC2 and it seems that the power management options appear on their own tab. My D975XBX "BadAxe" motherboard has an Intel gigabit NIC. I've found posts alluding to (some) Intel cards having a "Wake on directed packet" option, but I haven't seen anything like that on my Vista setup.

p.s. I don't have MCE2005 to verify that my rig works under that setup.
