Why don't you just download the ampr.org file from ucsd.edu. It's not so
large that any modern disk can't handle it. Pick it up once a week or so, and
you should stay current enough for your purposes, and you can then provide a
service to your community.
Alternatively, you could set your server up as a secondary to the ampr.org
nameserver at ucsd, and let it check for zone transfers. But I would think
that you would want to get permission first, since you would represent some
additional load on their system.
