I have a diskless frontend that works just fine. Not even CF - it
boots with PXE. Myth doesn't require a local spool of disk
space. It was running 100 mbit at first, and it got much much faster
after moving to gigabit. Things like the EPG, videos starting, booting
up, menus, etc. all became more responsive. I wouldn't recommend 
diskless over wireless, but maybe out there has experience with it.

HD can use up to 20 Mbit/sec. 802.11b won't work at all,
but maybe 802.11a or g will with a very good signal and nothing
else using the wireless 'shared' bandwidth. There's been lot of
posts in the past about wireless use - search the archives.
