Since almost all the code referring to PoD is in a place that only a 
devloper should look (in the hypervisor, and a little bit in the hvm 
domain builder), I think the naming (at least internally) is 
appropriate.  One could imagine "shadow memory" being mis-interpreted in 
a similar fashion.   :-)

PoD is only one piece of the puzzle required to allow booting 
pre-ballooned.  If you feel like we need a name "marketing name" for the 
whole feature to put in annoucements and changelogs, feel free to 
suggest one. :-)

In XenServer, the whole thing will come under the umbrella of "Dynamic 
Memory Control".

My guess is that Linux as a whole will have much less variance than 
Windows.  But we're not testing HVM Linux ATM.
