Supposing the domain has not been isolated, supposing you were trying to 
transfer the domain on an open link across a subnet to another datacenter 
(for migratory purposes to another location entirely) - is there not some 
kind of way of preventing migration, or am I being stupid, and everyone 
firewalls their server to prevent this?

I say this as my Xen units are on a private network, completely unfirewalled 
at this time, and am considering going live with a public IPv6 
implementation.
