[Mailman-Users] distributing to sub-lists via headers

[IOhannes m zmoelnig]

hi list!

my problem is such:
i want to set up a list with several sub-lists,
for example:
"mylist" (parent)
"mylist-dev" (child)
"mylist-announce" (child)

if a mail is sent to "mylist" with a header like
[dev] or [mylist-dev] it should be resent via
the "mylist-dev"-sublist.
the same for the announcement-list

additionally i would like following "mylist-announce" behaviour:
if a mail is sent to this list, it would be distributed via both 
"mylist" and "mylist-announce", but only once to members who are 
subscribed to both lists (i think this has been discussed on this list 
before with the conclusio, that someone's patch didn't make it into 
mailman-2.1 but i have lost those mails...)

is this possible ?
i am currently using mailman-2.0.9-1 on a debian/woody system.
