We have a scenario that is somehow equivalent to a very large enterprise
with many branch offices connected together by a private IPv4 only 
network.
An important characteristic is that there are no communication with the 
"outside" world,
neither in v4 nor in v6, and this is by design. By outside, I mean 
outside of the enterprise,
not outside of 6to4 2002::/16 prefix)

I agree, this is different from the original intend of 6to4, and it is 
based
on the premise that there are no communications to the outside world,
neither in v4 nor in v6, except via IT-controlled proxies.

In this scenario, 6to4 does marvels. Deploying IPv6 in a branch office 
is a 5 minute job,
that is done by configuring 6to4 on one access router. However, I share 
the concerns
of many that in other contexts, 6to4 may not be as desirable, 
especially if external connectivity
is required.

The point I'm trying to make is that one should not confuse, as Pekka 
did,
the protocol with how one could use it.
