I wanted to say at the mic.

I read this mMAG draft.  I also read the netext wg ig pmip prefix
delegation.  Additioally, I co-authored another draft about pmip and
network mobility.

I think overall we may have an issue here about the lack of a problemm
statement draft for pmip network mobility.  I do not consider it
blocking but it does backfire a bit here, if I can say so.

One interesting aspect of mMAG (other than that it can work) is that it
does not use DHCP at all.  You Raj asked which operator would be
interested in this mMAG concept - well any which does not implement
DHCP-PD today, and there are many I think.

One differentiating advantageous aspect in the netext wg item pmip
prefix delegation is that it delegates a v6 as well as a v4 prefix.  But
it has the inconvenient of requiring mandatorily the GRE encapsulation
(other kind sof encapsulaiton exist as well.
