Sigh...of course.

Ok, definitions, definitions...

I think a stateless query protocol can go over a stateless transport protocol.

What I (according to my definition) think was done with HTTP is a stateless query protocol over a stateful transport protocol.

And given the depletion of IPv4 space when people started to use each others IP addresses, the situation will not be better, but worse, pretty quickly.

I guess my statement of IPv6 is similar to yours above about "slow links" :-)

At least buys us time.
