I think I'm getting close -- so far I've done the following:

1. Disabled the "-subscribe" email address for the list.

2. Edited the list info page to remove the signup option and
replaced it with a notice that membership is via invitation only.
(I found the file to modify is /etc/mailman/en/listinfo.html.)

3. Made sure the list is not advertised on the site-wide web page.

4. Used apache to impose a name and password for web access.

This pretty much leaves the "subscribe" option in the email
interface as the remaining loophole. I would need to modify
the Mailman source to remove this keyword, and to modify
the "help" file that users can request. (Anyone know offhand
what files are involved?)

Of course I could just disable the "-request" address for
the list, disabling the email interface entirely. I'm a
little reluctant to do this, though I expect that at this
point most users will want to use "thuh web" to manage
their options.
