To help combat this our robots.txt is a CGI which returns disallow /
when it can figure out that the host being requested isn't supposed
to be indexed... one thing I look for is a Host: header... but none
of the big search engines send them.  yet.

I guess robots.txt is from pre-CGI days... the "Useragent" thing
seems more than a little useless.
