6to4 stats found, are there other places?

[JORDI PALET MARTINEZ]

Hi Ole,

If the problem is filtering, as expressed by Geoff, then we should kill
any protocol that can be filtered ?

I'm not going to repeat myself here, and I'm not the only one objecting to
this document in v6ops, so there is no consensus.

Regards,
Jordi
