Mailman equivalent of Yahoo "Special Announcements"?

Hi,
I'm about to migrate a Yahoo Groups mailing list to mailman. Yahoo Groups offers four delivery modes:
- individual emails
- daily digests
- no mail
- special announcements only
and I have list members set to all four of them. The first three I can easily deal with, but I'm not sure how to handle those set to the last.
As far as I can tell, the only difference between a Special Announcement and a regular post in Yahoo Groups is that a moderator can tick a checkbox when writing a Special Announcement on Yahoo's web UI.
I've scanned the FAQs and can't see anything obvious about this, nor can I see anything in the mailman web UI. I could just decide not to support this special announcements feature, but if I wanted to support it, what would be a good approach? The only thing I can think of would be to create a second list, mylist-announce, and subscribe everyone to that as well as mylist. But that makes user management tricky, requires new members to subscribe to both, unsubscribe from both, etc.
Have I missed something obvious? If not, is there another, simpler, work-around?
Thank you,
-- Steve

The closest thing to the latter is the Urgent header, but IIRC, that only bypasses digesting rules. I.e. digest members will get an immediate delivery.
It would be an interesting feature for MM3.

It also attempts delivery to members with delivery disabled. I.e. a post containing an
Urgent: password
header where password is the list's admin or moderator password (should that include the relatively new poster password?) will be sent now to all list members regardless of status.
Note that this must be a real header. A first body line pseudo header doesn't work here.
So, it seems that we can't completely emulate Yahoo in that we don't have the ability to disable all delivery as opposed to disable delivery for all but Urgent messages, but maybe we're close enough.

From the Mailman side of thing, I imagine the 'easy' way of emulating this is to have an announce only list, for all members (with bounce processing etc disabled).
I think most Y! groups subscribers would use "special annoucements only" for lists too noisy for them, but still want to hear about important things.
create a second list, mylist-announce, and subscribe everyone to that as well as mylist. But that makes user management tricky, requires new members to subscribe to both, unsubscribe from both, etc.
The sync_members script (and cron) might be useful hereā¦

Do you ever send special announcements? I'd be tempted to just set those people to no mail.
