Correct.  Besides a jobqueue, the only duties a slave backend (with 
digital/mpeg tuners) has is file shuffling.  Nothing intensive there.  
Atoms are not recommended for frontends, because if whatever hardware 
accelerated decoding method you are using fails for any reason, be it 
incompatible codec, incompatible compression options, glitchy stream, 
use of flash that cannot be accelerated, the Atom does not have 
sufficient power to fall back on for much of anything.

If you already have the hardware in hand, you should be able to run a 
jobqueue-less slave backend without much trouble.  Otherwise, look into 
buying some real hardware instead.  A bare Core 2 or AMD system can be 
brought in under 40W idle, and an i3/i5 system at around 25W idle.
