I'm more interested in allocation of address space to these devices instead of domain names. These devices *must* have globally unique addresses. CIDR, NAT and other technologies that have slowed the consumption of IPv4 address won't help you here.

Sure they could. It just becomes a directory lookup, with roving physical addresses. Rather than give you my IP address, I give you a means of contacting me -- a phone number, a skype alias, whatever. When I establish a net connection, I register that location with my directory service, and that registration may be NAT:someopenport.

They have to have globally unique addresses, but the address space does not need to intersect with the other globally unique address spaces.
