Re: "non-authenticated" tunneling [Re: draft-durand-v6ops-assisted-tunneling-requirements-00.txt]

Agree ... actually I believe I mention this case in the sense that a non-registered mode is very easy to implement, same as a 6to4, and ISPs could only go to offer this if adds not overload to their work.

I know ... the workload can come by abusers of the service, but some times is much easier to have a non-registered service and then either allow the service only in "own" network or filter offending users, or whatever.

Jordi
