Hello Thomas,

You seem to be concerned that if we change this value in
the base Mobile IPv6 specification, then suddenly it won't
make as much sense to change it or otherwise specify it
in a future ND document.  I think that it patently untrue.
So, I strongly believe that we can have a good base Mobile
IPv6 specification that works, without impeding future progress
on more general ND solutions.  Why not?

Then let's keep a sentence in the specification that makes this plain.
It would not impede progress on ND.

It is critical for the one change for frequency of router advertisement.

I think 6 days would be better for the particular point about
router advertisement.  I'm classifying that differently, because it
is required for sensible implementations.

If you want that one in a separate document, then I can have it
for you on Saturday.  I'm concerned, though, that the document
would be viewed as a place to put other things that aren't so
plainly required.
