Yes, but with a minimal state...

It is as stateful as FTP, having a minimal state, too.

We moved from a ("papercut" based) dedicated NNTP server implemented
as a ZEO client (the type of solution, you currently seem to prefer)
over to a ZServer based NNTP server on top of ZPublisher.
And we were very pleased with the transition: both with respect
to maintenance as with respect to performance....

Yes, we have to maintain a minimal state (for NNTP, this is,
user identity, selected group and selected article) outside
of ZPublisher and provide access to it via request and response.
This is managed within a few dozens lines of code.
