Need a way to save and load memory

Greetings Sun Managers,
I have an unusual application. I have several solaris 10 zones that were
designed to be used as demo servers. The idea was that our sales force can go
onsite, quickly create accounts and allow the customer to try our product in a
real way, however none of the data they enter is saved to disk, it all resides
in RAM. So long as the demo zone doesn't reboot everything is fine, it'll keep
the information, but if it reboots all is lost and they have to start over.
Now, clearly the simple answer is "Don't use a demo to store important
information" but that isn't the answer they want.
Is there a way to snapshot RAM, save it to disk and then reload that RAM
image to restore all the resident memory? Clearly a savecore will save the RAM
but is there a way to reload it? What about power management? Is it possible
to force the zone to go to sleep, save its instance to disk and then reload that
instance like laptops do?
Please email, I'll summarize and send back to the list.
Regards
-Bob
