There many reasons to disagree with 'ICN has overtaken DTN' (embraced in
some contexts might be a better way of saying it, and it surely depends
on which ICN flavor you choose).  But that's immaterial considering what 
we observe right now as the energy level.

As we discussed among the chairs and Lars, we should not hang in a limbo
state but rather be (1) or not be (0).  At present, my sense is more on
the 0 side; we also see on the research side that the activity level in
this field has gone down.

I believe that the concepts (and notions of protocol robustness)
discussed in the field (irrespective of the bundle protocol) remain
valid and useful also the Internet at large.  So, we have done our
share and we spawned a working group.  Time to take a break, declare
success, and go home.  As Will put it, perhaps something to return
to in the future.  We'll see.
