I don't really see an overlap with the distributed news effort at this
point. We are right now trying to decide on a set of primitives needed to
support a reading interface-- eventually I hope to see us implement these
primitives in a real environtment to see how they work. What we are not
doing right now is anything involving the database or the transmission of
articles between systems-- all of the functions of uucp, inews, rnews or
the batching subsystems. We are simply trying to find some way of building
an interface so that rn, vnews, readnews, or whatever can use a set of
function calls to do their work without worrying about what is on the other
side of the functions-- it could be a library interface for a single
machine, a client/server on TCP, a distributed file system or something we
can't even imagine now. What we are trying to do is isolate the reading
programs from making assumptions about the database so that we can install
an interface between the database and the reading programs for whatever
environment is appropriate without changing either end.

Deadbone erotica is the prickly panic of forgotten milleniums, it is the moldy 
billion year madness that creeps deep along the spinal behind of my mind.

	What I meant to convey (and apparently failed) was that a large
part of the distributed netnews talk has centered on a protocol between
a client and a server. It seems to me that this may ba analagous to the protocol
needed between a remote site and the "new repository" for requesting missing
articles. I realize that there are substantial differences, I am merely
wondering out-loud (?) if the common parts of both protocols
(SEND-ME article 133 in net.wizbang) should be the same.

If you're thinking of using something like this for requesting old
articles, be sure to address security.

Right now, netnews is send-oriented.  Each site, when it gets an article,
decides who it wants to send it to and sends it to those sites.  The
receiving site can throw away some things it gets, but it can't request
extra information.

If you allow sites to request news by newsgroup or message-id, the
possibility exists for these sites to somehow discover the newsgroup
name or message-id of private, locally distributed articles that they
aren't supposed to get, and ask for them.
