Fred,

I'm not keen on specifically listing _any_ RFCs in the charter. It just
doesn't add meaning at this stage of the WG lifecycle, in my opinion.

How about a simpler:

  A number of approaches are being looked at in parallel in other
  contexts. The IRTF RRG examined several proposals, some of which were
  published as IRTF-track Experimental RFCs.

This provides the reader of the charter with knowledge that there is a body
of work "out there" and points to the RRG as a place to look first. Beyond
that we would probably fall into the trap of listing almost every RFC that
has (had) anything to do with scaling, EID/LOC split, encapsulation .. .. ..
etc.

Cheers
Terry
