Hi Paolo,

I for one fully support taking on dLife as a DTNRG draft, and I look
forward to working together with you to try to get it through the
whole process a bit quicker than what was the case for PRoPHET. :)

I also still think that creating a common routing framework as
discussed before would be very beneficial, and I believe that Elwyn
and Avri are also still interested in this. I've been very busy with
other projects since the Mountain View meeting, but your timeplan of
having a -00 version of such a framework ready for the March meeting
seems very reasonable, so let's work towards that.

/Anders
