This, along with RFC 4941's observation that there may be utility in an IID that is not tied to hardware identifiers, would appear consistent with the thought and recommendations of
1498 On the Naming and Binding of Network Destinations. J. Saltzer.
     August 1993. (Format: TXT=24698 bytes) (Status: INFORMATIONAL)

and the definition of an Endpoint ID in
1992 The Nimrod Routing Architecture. I. Castineyra, N. Chiappa, M.
     Steenstrup. August 1996. (Format: TXT=59848 bytes) (Status:

The latter is the origin of the question of a locator/id split; a locator identifies the location of a network point of attachment, and an identifier in essence identifies what we might call a "socket". Imagine - although I can't say I know *why* someone would want to do this <sarcasm> - one wanted to move an application from one physical or virtual machine to another. If the identifier could move with the application, that would simplify such motion.

Note that the NIMROD architecture and Saltzer's document are not fundamentally about security. They are about scalable management of applications interconnected by a network and routing in that network.

If at first the idea is not absurd, then there is no hope for it.
