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.
