There was discussion of extending the swap daemon (sorry, also don't know the official name off the top of my head) to handle PoD, since PoD is essentially a degenerate case of swapping, but it hasn't happened yet. In any case it will need to be tested first, since it may cause boot time for pre-ballooned guests to slow down unacceptably. -George
