Hi,

the goal for TANA and ALTO was to identify some subsets of the overall  
problem space that are sufficiently well understood that we can start  
to architect solutions. (And limit ourselves to those subsets where  
the IETF would be an appropriate body for this work.)

There are certainly other parts of this problem that may be ripe for  
discussion in the IETF, and chartering TANA and ALTO by no means  
precludes this discussion from happening. I fully expect the IETF to  
take on additional work related to this general problem space in the  
future - we just had to start somewhere, and TANA and ALTO is where we  
started.

I'd strongly encourage folks that want to push forward additional  
proposals for the IETF to take on in this space!

Lars
