Hi Tony, I think you're making very valid points.

Experience in European NRENs is that in the absence of native university
links, manual tunnels are used, rather than 6to4.   Here, the rate of
change of tunnel configuration (add/delete) is important, and I think the
DFN had the largest count at some 300 enterprise sites (which interestingly
have largely been moved to production addressing from 6bone, so there's another
lesson to be learnt in there...).   Routing also has to be configured for
any university site attaching natively anyway... then there are other
resources required such as addres space allocation/management, etc.

I agree SOHO networks where the ISP has (tens+ of) thousands of customers is a
different case.
