I've started to sketch out some requirements for improving the virtual
hosting support for Mailman. It's not finished, but I'm soliciting
comments anyway. Please see
http://www.zope.org/Members/bwarsaw/MailmanDesignNotes/VirtualHosting
and please add comments to the Wiki page.
I'm not sure whether this stuff will make it into Mailman 2.1 or will
have to be postponed.
Cheers,
