I dunno.  If you're planning a quick call to various backbone sites, any
dummy message with the same article-id as the nasty message should do the
trick.   The dummy message will propagate on normal channels (possibly
use a distribution of news.config which is supposed to have extra links)
anywhere the real message hasn't arrived.  If it gets somewhere the real
message is, it will stop there, but I'm assuming that the message has
already made it out.

Of course this gets very tough to coordinate with a cancel, since a cancel
crossing paths with the dummy would cancel the dummy, and on a batched
news system, stop it from travelling.

This isn't great, but it would work now.

To solve this you create a control distribution for dummy messages that
is widespread, moves fast and is NOT batched.  (In fact, even invoke uux
without waiting if you want!)

This would work without any software changes.
