Heh. It was my hope to come up with a patch by *tomorrow*, but that
involves clearly understanding points 1-3 to come up with a
future-proof solution.

Can you expound on what ahcpd's future is going to look like, and I'll

What, in particular?

I am doing several things differently than the default in my own
version of the package, notably enabling link state detection by
default and also telling it to just
propagate /64 6to4 addresses by default:

# If you have a 6to4 address autoassigned from the openwrt 6to4 script
# this will automagically pick it up. This will also pick up 2002 nets you are
# serving

redistribute local ip 2002::/16 le 64 metric 128 proto 0

# if you are on a gateway, uncomment this
# redistribute local ip ::/0 le 0 metric 128 proto 3

# if you are a 6to4 gw, you are unique and COULD distribute the 2002::/16 route
# to all interested clients, but I'm not doing that yet
