Hiya,

I had a quick read...

My main comment is to say thanks! It's great to see people
document paths-not-taken like this and in such detail.

I have one suggestion as you head towards finishing this
work: if you were happy to generalise a bit more in your
conclusions that could be useful - in particular if you
could try characterise the kinds of IETF protocols (or
features of those) that might or might not be suited for
use of RRM, that could benefit the community.

Cheers,
S.
