... FWIW, I never said I thought it was the right answer :-)

But my point in writing was mostly to say that I encourage postponing 
"transport-aware" work until we make some progress on 
"transport-unaware" SHIM6, and then making sure that, wherever the work 
gets done, we are working closely with the transport community to meet 
their needs with protocol mechanisms they will actually make use of.
