A gateway between HyperNews and News is possible. (A similar Email Gateway are already available.) Each News group would have a HyperNews forum to represent it, and each article in the News group would have a corresponding HyperNews message in the forum. When a HyperNews reader adds a message within HyperNews, this could be automatically posted in the corresponding News group. Cycles must be avoided, as usual in bidirectional gateways.
The HyperNews/News group should have a fairly short expiration until we have some way of automatically organizing messages. Obviously a site supporting the HyperNews/News gateway for a group must either store all the News articles or have access to them from somewhere else.
For any moderately large newsgroup, we should probably subdivide a single newsgroup into several HyperNews forums. Even a relatively low volume newsgroup accumulates a lot of articles over time, and these need to be organized in the archive. But this requires that someone (or something) read each of the articles to find out which HyperNews forum it belongs in.
The best approach to implementing this gateway now is to use the NNTPClient.pm module, similar to how the POP3Client.pm module is used to fetch mail in batch-fetch-pop-mail.pl. Another approach is to use an IMAP client.
