I was wondering about that. I have a workstation which I would contemplate 
putting a back end in if I knew the MBE would understand the various states it 
could be in.

1. Me working and SBE available, manually started and stopped.
2. SBE invoked by master, recording and shut down afterwards.
3. Powered down by me, but available if MBE requires it (woken up by WOL code).

Obviously, there could be times when I went to shut it down while it was 
recording, where it would need to remain awake until the recording+optional 
processing had finished, then shut itself down. Presumably this could be 
achieved by the use of a cunning script. Thoughts?
