vnews and readnews are part of BNEWS. CNEWS has its varients.
rn 4.3 came with BSD 4.3, and a patch kit to make it work with nntp was
packaged with nntp for awhile. However, rn was not and is not part of
the news distibution, per se.

Go read the document on the news software. It is posted monthly to
news.announce.newusers.

The biggest problem with nn and trn is the fact that they (currently) have
incompatible thread databases. In fact, it would be a pretty neat idea
to build some kind of standard interface for doing this kind of thing
so that it could be ported to more news readers or architecture other
than Unix! We might be able to move some of this proposed standard 
interface back into NNTP. However, Unix NNTP has enough problems trying to
cope with the differences in the two BACK-end (CNEWS and BNEWS) to be
mutilated into supporting two different threading architectures.

I have no experience with trn, but we have one machine on campus which
uses nn.

It consistently consumes more resources (by number of articles
requested, cpu time, connect time, you name it) than any other machine
on campus.  The number of readers on this machine is only a fraction of
the next runner up though.  I assume that this is because nn reads ALL
article headers off the server regardless of wheather someone want's
them.

Is anyone working on a better nntp-nn interface?  For that matter just
a better caching stratagy would be nice...  Does nn use XHDR to grab
groups of headers deemed importaint?  Could it be set up to cache only
locally read newsgroups?  Perhaps only asking for the headers when
someone read's them?
