A somewhat related scenario i had considered was to use  an atom based
system for the backend and then a more powerful Intel or AMD dual core
system for the frontend (Non-myth requirements made it so an ion based
system wouldn't work). Commflagging could then be run on the frontend,
and it could be shutdown and started up as needed. Also since the
backend would be low power it wouldn't hurt to leave in on most the
