Re: [Dime] Rechartering:draft-sarikaya-dimeradext-prefix-auth-ps-00.txt

Hi Julien

You'd better keep the draft
http://tools.ietf.org/id/draft-korhonen-dime-pmip6-03.txt
in the current scope, and not mix with prefix delegation.

LMA prefix delegation is a separate topic which  probably
involves DHCP/RADIUS/DIAMETER  methods
