This is difficult to do for various reasons. The main issue is gating to
news is asynchronously done by a separate process. Even if the process
could reliably determine that another gatewayed list in the installation
was a recipient of this post which it could only do by examining
explicit addressees and the other list might be a Bcc:, we'd still have
to arbitrate somehow which post gets gatewayed to the multiple news
groups and which ones get dropped. Although I suppose we could send each
one for all the news groups and let the news server figure it out.

Anyway, I don't plan to try this.
