Nico, while I agree that work in BTNS is important, and while I agree that all needs to happen, I actually think that there is more to helping these requirements than a small number of technical point solutions. I'll note that the OSPF case was difficult even though it really didn't have connection latching issues (you protected all OSPF traffic) and did not require leap of faith. So, I agree that BTNS is part of the picture. But don't under estimate the importance of conceptual models, BCPs like Steve Bellovin's use IPsec document, etc.
