gnus-multdom.el anyone...?

When wandering through Noah Friedman's emacs lisp page
        http://www.splode.com/users/friedman/software/emacs-lisp/
looking for vcard.el, I found this little critter:

vm-multdom.el 

       This package lets you reply or forward messages from within VM,
       setting your return address to match whatever address was used
       to reach you in the first place.

       For example, my regular address is
       friedman@splode.com. However, I still sometimes use the address
       friedman@prep.ai.mit.edu when I'm sending email that's related
       to the GNU Project. Using this package, if someone sends email
       to the latter address, my From and Reply-To headers are
       automatically filled in with that address so that it looks like
       I am continuing to correspond from MIT, even though the rest of
       the time my correspondence looks like it comes from my regular
       address.

       In order for this to work, all you have to set a lisp variable
       to contain a list of all your known email addresses and load
       this file as part of your emacs initialization.

This is a feature I would have liked to have in Gnus.  What I do
today, is to redirect different addresses into different mail groups
and then use gnus-posting-styles to set the sender address.

But occasionally things end up in the wrong group and my sender
address changes and this may be confusing.

Is there a way already?  All hints and tips are appreciated as always!
