Like an IXP infrastructure you would still have to configure these
peers, and thus you will just have to automate it, which is something
you want to do anyway if you want to scale in any matter or form...

As your BGP peering will be between two 6to4 participants the packets
will be sent directly between the 6to4 nodes as they know how to reach
other.

The fun with using 6to4 addresses of course is that you for almost sure
get stuck to a 1280 MTU which is very non-optimal.


Better to then just use proto-41 tunnels and put the tunnel set up in
the automated setup mentioned above.
