Our current addresses stop working on 6/6.
So that means add new tunnel, add second prefix on most subnets, wait
util 6/6, deconfigure the 6bone prefix. That's arguably no harder
than just setting up the new prefix and removing old at once.

It's not, but 1.6 is kind of crufty now.

I have a tunnel from t1.ir.bbn.com to sunpal7.mit.edu with peering,
and I intend to maintain it. But I don't think that bears on MIT
address space since I don't think it would be polite to OCCAID to use
MIT's free allocation at BBN.

The existing system seems to be that 18.x is 3ffe:1ce1:0:X::/64, where
X is the same value as x, but of course written in hex.
I would suggest that someone design a new scheme, or republish the old
scheme. There may be subnets with less than 16 bits of host space,
and therefore more numbers than would fit using the above scheme, and
there's a need for space to hand out to remote people etc.
