I run the scheduler on a Kirkwood without any problems.  It takes longer than 
a spiffy new machine.  Just checked my logs and the last run took 11.6 seconds.  
This is using an SSD on real SATA (not usb based).  When I ran it on a normal 
HD, it took 40-50 seconds.  

I'm not sure that I'd like to have my storage on a machine that that powers on 
on-demand.  Does anyone do this? I'd worry about lag on viewing.  Does myth 
know how to wake storage on demand? 

You might need to have your storage box on all the time.   If storage is on a 
machine that is on all the time, might as well just run the backend on the 
storage machine.
