Hi Dan,

   Many people split the Web and email portions of Mailman up,
   running each on its own server.  That's what I do at mallorn.com,
   and here at NCSA we're taking it a step further with four 
   mail servers and three Web servers (round-robined) all providing
   the same functionality.  Of course, the glue that holds it all
   together is the filesystem (we tried doing Mailman in AFS, but
   it was a pain getting our patches to work on new versions...  We
   ended up having to settle for (ick) NFS).
