Agreed, that's a great idea. I could have a common lib under 
examples/vm_power_manager, then two apps, vm_power_manager and 
guest_cli. That would keep everything nicely local, and not expose the 
channel API publicly. The only reason we were making it public was to 
allow "make" to work, so that's not a good enought reason, tbh. I'll 
throw a prototype together today.

Thanks,
Dave.
