Great :)

I'm certainly willing to help out here.
 
For the problem of routing in that environment (at ROLL) we produced no
less than 4 requirements drafts, and that certainly helped a lot
figuring what was left to be done. This is because wireless (even Low
Power) is so diverse in its usages and constraints. Following those
tracks we could:

* go back to the requirements we have on transports for the flows we
know of

* see which ones can be accommodated with existing transports and flow
control techniques - produce BCP there - 

* and then see if additional work is needed to accommodate real world
constraints like very femtomatic buffer capacity in the intermediate
routers, and randomized path diversity.

Maybe we could organize a BAR BOF in Anaheim?
