And there is one big win with the manager UI - you can actually SEE it
running.  In demos, I have used that UI to make the point "I have a whole
cloud architecture running in 6GB of RAM, see it right here".

Plus, VB is available on Windows and Mac, the majority of end-users should
be Windows based if we do our jobs right (80% of the developer market still
runs Windows).  So, teaching people with VB is more "portable" across
operating systems.

In any case, I am on VB now, I will see if it is more stable than xyhve.

The sleep/wake thing is HUGE for me as I often move from demo to demo by
closing the lid on the laptop.
