Oh, this was precisely what I was planing on doing, I'd assumed it was 
possible.

I had wanted to have a headless Master BE on my VIA Samuel 2 system with 
a genuine raid card, a GigE card and a AverMedia USB2 DVB-T (only 2 PCI 
slots) and 2 diskless combination FE/BE on 2 old P!!! 667s with plenty 
of PCI slots and PVR 150 or 500s in.

I had wanted the FE/BEs to shutdown automatically when not in use and 
have the master BE WOL them when they were needed for a recording or to 
help out when the transcoding or commflaging queue got too long.

Is this really not possible? What would need doing to make this work?
