I would really prefer a model where the user can create a list on
their own, adding subscribers, changing options, etc.  The admin
would then be sent an email message and he/she could enable the
list.

One component is critical no matter what approach is taken...  Mailman
needs to have some sort of routine that checks against a file containing
already existing addresses ( anything aliased or in /etc/passwd in most
cases).

I personally find it easier to create a new list on the commandline,
but I'd rather punt the entire job (except for aliases) to the end user.
Otherwise I end up sending questions back and forth, etc...
