Re: [Trigtran] FW: [dhcwg] Announce: BoF Proposal: Detecting Network Attachment

Dear John,

I'm trading e-mail with Greg Daley, and I do believe there is a linkage,
although DNA is focused below transport - they are more about address
management, for instance, than about transport notification. I look forward
to sitting in on their BoF in Vienna.

Thanks for bringing this to the attention of the mailing list - I was off
the net for a week in New Mexico (there are still some places that don't
have phones or cell coverage)...

Spencer
