Tony, I didn't take this off-list yet since a small group hasn't
stabilized. I figure you'll say when.

I would be interested in exploring the scope of "routing" in the modern
Internet. The RRG "is chartered to explore routing and addressing problems
that are important to the development of the Internet but are not yet
mature enough for engineering work within the IETF". I know we've always
meant IP routing and addressing, but there is a lot more "routing" going
on. For example,

  - multi-layer routing (using information from multiple layers)
  - research in SDN routing
  - explore the many things BGP is used for, for new meanings of "routing"
  - ICN (information-centric networking)

Routing in ICNs is full of ideas, some of them repeating what we went
through with IP, e.g. Dave Mills's dynamic hierarchical routing (I don't
recall exactly what he called it). I haven't seen two-byte PIP come back
from the dead but I wouldn't be surprised. ICNRG meets regularly at IETFs
and SigComm. A couple of joint meetings to argue about routing would be
quite interesting.

Then there are IoT, DTN, satellite, and other self-assembled meshes - all
possibly interrelated.

Finally, routing for privacy. We have lots of efforts to distribute traffic
to avoid surveillance. How could routing contribute? This might build on
BGP multiple paths, or maybe source-asserted trees.

That's all I have right now.
