Hmm. By that standard, it would seem that Diameter is RADIUS, too...

I don't think that I said anything about good or evil :-), but you make
my point for me: IPv6 is hardly "backward compatible" w/IPv4 & that's
not a problem. The problem would arise if someone claimed that it was
because, 'Well, you can build a gateway'.

Certainly, in that RADIUS (the RFC 2865 version, anyway) only allows UDP
transport. How could I have missed that? ;-)

to unsubscribe send a message to firstname.lastname@example.org with
the word 'unsubscribe' in a single line as the message text body.
