Personally I can't see why people are so interested in the PI as a 
solution but do remember you need arm drivers for the S2 usb cards. Do 
they exist?  I don't understand why you have a VM environment which must 
run on a powerful'ish computer, then want an underpowered computer for a 
slave.   I personally am interested in arm... and therefore looking at 
the cotton candy or samsung arndale.

Personally I use local disks (on a slave) for recordings.  You can store 
on a nas - but do think about performance if you have a few nas clients 
around the house.  You could end up stuttering during play back of HD. I 
have RAID devices in my linux server for data I do not wish to loose, if 
I loose my recordings disk, it really isn't the end of the world.

Best frontend for Mythtv ... guess what..... it's mythfronend... I have 
had a play with Frodo (out of curiosity) and came back immediately.  
Just doesn't work as well, the features in MythFrontend are not 
replicated.  Have a play see what you think.

I would recommend you either stick with a low powered intel solution or 
looked at an Arm board with sata for a slave.  You've outlined an 
architecture which could be challenging - not where I would go.
