ietf-nntp Virtual hosts in NNTP servers

[Joao Prado Maia]

I know this is not the best time to go over something as huge as this, but 
did anyone think of implementing a way for NNTP servers to accept clients 
in multiple named servers ?

Most of you guys probably know about the 'Host' header that gets sent from 
HTTP 1.1 compliant browsers, which allows web servers to serve pages for 
different domains while binding to the same port in the same IP address.

Could the same thing be implemented for NNTP ? Can anyone provide feedback 
about pros and cons about this idea ?

Regards,
Joao
