During the meeting there was talk about unnumbered interfaces.  Trying 
to understand them leads to the posted informal Cisco pointer:
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094e8d.shtml

And a search at tools.ietf.org leads to RFCs:

CR-LDP, RSVP, ptp-over-LAN link-state, RIPv2 MIB, OSPF/FrameRelay, OSPF 
multi-area adjacency, GMPLS.  One wouldn't make the AUTOCONF ad-hoc 
addressing architecture dependent on e.g. OSPF/FrameRelay.

But that's just an opinion of course, and technical advantage could be 
discussed... e.g. the change of src address was discussed - why is this 
feature needed?

If we need that feature of change of src address - how could that be 
achieved without unnumbered interfaces?
