	Indeed, it's a hack.  Thanks!

	I'll try to check it.

	I'm also planning to get into patching INN to support such a
	feature.  I haven't looked at the source yet, but as a rough
	guess, I think it might be implemented as a storage class
	option...

	It leads me to the question, how does INN handle messages,
	cross-posted to the groups, belonging to different storage
	classes?
