This will be done at some point.  "Autoballooning" requires the guests to 
report their current usage statistics back to dom0 (using the control 
interface, which all guests have).  We'd then have a daemon in dom0 that 
would receive these messages and send ballooning messages periodically.

The daemon in dom0 could then be set up with some sort of policy 
configuration, regarding minimum / maximum footprints, relative importance of 
the domains, etc.

Right now it's probably on the TODO list somewhere, waiting for someone to 
volunteer ;-)

Cheers,
Mark
