|what does trn offer over nn?  We've been running nn now for almost
|a year - without any problems --

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?
