I already responded in the launchpad bug, but actually, I think they're 
pretty similar, only dlists only uses the listname+topic email format to 
designate sublists/topics, and the current scope of what we're doing 
doesn't look at archives, just about delivery of mail to users who may 
have chosen only some topics they want from a given list.  I think it'd 
be easier to add the prefix and archive capabilities once we have dlists 
working with Mailman 3.

We already have the dlist code for Mailman 2.1 (and I believe that's all 
available on launchpad somewhere; ping me if you can't find a link and 
want one), and we *did* have a Google Summer of Code project aimed at 
porting this code to Mailman 3.  Unfortunately the student was unable to 
complete the project (for personal rather than technical reasons which 
it would be impolite to share), so two of us from Systers are working on 
the port.  The architecture looks compatible and we've got our best 
guess on the necessary data structures/database tables now.

We're hoping to have it done in January and are actively working on it, 
so maybe it'd be best to wait 'till that port is done and then look at 
what will be needed to extend it?
