Well, I think address sharing is a one-step-further consideration.

The basic problem here is IPv4-over-IPv6 in a stateless way so the concentrator/AFTR doesn't need to maintain address/port mapping.

I'll read the draft and get back.

The problem space of 4rd is that 4-over-6 with stateless IPv4 address sharing mechanism.
Please take a look at http://tools.ietf.org/id/draft-despres-intarea-4rd-01.txt
