I suspect you mean an "impending" HD TV purchase, not an "impeding" one :-)

I haven't played with the SheevaPlug units, but I have done a lot of work with 
the NSLU2s, which are very similar. The problem is the USB subsystem is very 
slow, and using USB drives may result in inadequate preformance.

The NSLU2 has no floating point unit, I'm not sure about the Sheeva, but the 
lack of an FPU might also preclude some B/E functions.

My guess is you want a somewhat beefier computer. The Sheeva looks 
interesting, but very limited.
