Couldn't this dispatching be done by means of the splitting code?  Ie,
all mail sources plonk there mail into the splitting code where it is
decided in which backend it should end up in, and to what group in
that backend. This would also give us a backend-independent
mail-splitting code.

Something like:

(setq gnus-mail-sources '((pop :server "some.pop.server")
                          (group :name "nnimap+pdc:INBOX")))

(setq gnus-split-rules '(("nnml:private"         "To: jas@pdc.kth.se")
			 ("nnml:sendfail"        "MAILER-DAEMON")
			 ("nnfolder:sent-mail"   "From: jas@pdc.kth.se")
			 ("nnimap+pdc:lists.\1"  "owner-([a-z]+)")))

I see some obstacles, but the scheme as such doesn't feel extremely
complex which could be a good thing.

	* what to do if nothing matches?
	* how to handle crossposting?
	* what about fancy splitting?  (haven't used it)

Sorry if I'm completely missing the point and overlooking some major
issue..
