I've also got an article that will be going up soon on the LOPSA.org 
website that explains, in great detail, what we're doing on 
python.org and where I think we should be going.  If anyone is 
interested, I'll post the URL here when it's up.

You mean, do we do these things at the MTA level?  No.  The MTA has 
no clue as to who is a subscriber and who is not.  These things could 
potentially be done at the Mailman level, however.  Unfortunately, 
while you can configure Mailman to moderate (or reject) all posts 
from non-subscribers, I don't know of any way to configure it to do 
something like what you suggest based on the time of day.
