Decoupling is good, but it can go farther...
As I hinted at (oh so long ago) during my presentation at the AMS
workshop, one advantage of indirection-based approaches is that EIDs
do not need to be allocated hierarchically, thus the existing policy
constraints for address allocation no longer apply. The RIRs could
continue to hand out 'routing slot conservation policy'-constrained
LOCs since they have the technical expertise to know what this means.
They could also hand out the EIDs, but since the policy regime for EID
allocation is fundamentally different than LOCs, it might make sense
for other bodies (e.g., national allocation entities like NANPA in the
+1 telephone region) to handle that task.
Of course, if EIDs aren't handed out hierarchically, the existing ACL
models that rely on locator semantics would obviously break. Some
argue this wouldn't necessarily be a bad thing...
