I believe this kind of functionality should be a script/daemon,
like you have implemented it now.

xm/xend and xl/libxl toolstack are "single host" anyway,
so they don't really know anything about other hosts.

XAPI toolstack used in XCP (and in Citrix XenServer) has
multi-host pools, but I believe this kind of functionality
already exists there, and can be implemented as plugins.
