Nice idea.  However, how do you get at the machine to schedule
recordings, etc?   I usually do that via mythweb, at pretty random times
of day.  That would mean that I'd have to walk out to my living room,
turn on the myth box, walk back to my office and run mythweb,
remembering to shut the myth box down when I was done.  Not to mention
the trouble I'd have if I was on vacation and forgot to set something up
to record.  (ie. not a solution for me, but I run a small cluster in my
basement that's always on, and my myth box is an uber-quiet pundit)

On that note, though, adding in some power saving features might be nice
- spin down the hard drive, etc.
