Yep, we run something very much like the above here.  Users can
customize their settings (with an additional hack of my own doing for
my own person list) with a handy CGI.

I would very much like to see the above in Debian.  It'll make it a lot
easier to move off my existing Solaris setup and will allow more sites
to give control to their users, where it should be.  (Yeah, yeah, but Sparc
Linux was barely useful in '96 and I can't afford the downtime to format
for Debian now.... but I've also got 'buy new machines' on my wish list
