For me the first question is whether multicast in the LLN would be RPL-
dependent, or have RPL-like features (e.g. dependence on a DODAG).
That could argue for doing the work in ROLL or a follow on group
(ROLLMAN?)

At least some of the 6lo proposals (MS/TP comes to mind) are not mesh
networks, but still constrained from a host and bandwidth perspective.

I like the topology-independence of MPL, but I think work still needs to be
done to see how far it is from optimal (in terms of energy and bandwidth
usage) under different operating conditions and parameter settings.
