> Typically EID means address of hosts which can move between network locations.

I would argue it means an ID of anything. Traditionally, an EID is an ID of a host but has evolved into a VM, a service, and now more opaque objects per your draft.

> Instead we want EID to mean address of communication objects: mp2p queues and p2mp channels, which can move between hosts.

Right, exactly.

> This portability supports functional distributed programming models and simplified on-path compute aware networking.

Right an RLOC is an address pointer in a computer language and when you "deference it", you get the contents. But in a true virtual memory system the EID is an address pointer, and the OS finds where the contents are.

> On-path awareness becomes important in the absence of centralized clouds which hide DNS changes from clients, and contain the unpredictable latency of co-located HTTP redirects. 

Right.

> These geo-distributed compute conditions are relevant for the new AR/VR edge applications, and this specification simplifies the description of elastically scaling them using LISP.

Agree.
