One way would be to have your system subscribe itself to the tz
mailing list, and then poll the FTP site every time it gets email from
anyone whose email address matches the regular expression
'^olson at .*nci\.nih\.gov$'.  You can probably use 'procmail' to do that.

I'm not sure it's a good idea to do it completely automatically and
unconditionally, though, as there may be bugs in the official
distribution.
