All, Just to elaborate, there are two related drafts on this topic, http://www.ietf.org/id/draft-zhang-l3vpn-label-sharing-00.txt and http://www.ietf.org/internet-drafts/draft-zhang-pwe3-iccp-label-sharing-00.txt. Comments should probably go to both the l3vpn and pwe3 lists for now.
Mingui will have a presentation on these drafts in both the l3vpn and pwe3 sessions in Berlin.
