I see the basic "how do I let the right people post to this announce list automatically" question often enough to indicate that there is a perceived need.
Let's put digital signature technology to work.
For some post 2.1 release (and probably patchable into 2.1 by suitable people), extend the privacy options to include:
List (two columns...duplicate senders probably allowed for the case of a work key and a home key or an assistant's key for authorized forging, or whatever): Automatically post messages from these senders PROVIDED they are digitally signed using the key listed for the sender.
Checkbox: Automatically and silently reject (with logging) any message not from a listed sender and properly signed.
Variations (not silently rejected, etc, if desired...but sending a rejection message gives the would-be rogue poster information).
It seems to me that this can be turned into a suitable solution to the auto-moderated announce list desire, without a whole lot of coding.
I didn't see such a feature request on SourceForge...if I missed it I apologize (I've spent no more than 15 minutes driving SourceForge).
