Re: [MEXT] LISP as a solution for some part of the DMM requirement

Hello folks,

I agree that LISP work should not be done in the [mext]
working group.

However, if the LISP design shows how to make a good
solution for distributed anchoring, it is pertinent to
our work insofar as it provides a model for the [mext]
solution.  In that case, if we are fortunate, it would
be easier to devise an appropriate solution by using
the LISP distributed anchoring as a guide.

Please note that I do not yet claim that LISP does
what is needed -- only that we ought to take a look.

Regards,
Charlie P.
