Biggest problem with this idea is that there is a trend towards using
web forms for mailing list sign-ups (with email confirmation).  If
this becomes common practice, you will not have the opportunity to
capture the out-bound "subscribe me" data.

As for telling your local users that they need to register all list
servers or they will not get their in-bound subscriptions, good luck. 
Most ISP lusers never read the details of policies and such...  You'd
have to intercept the in-bound list traffic and send a notice to
anyone subscribed to an unregistered list.
