If they're CGI *scripts* then they just use the CGI environment, not
Apache, so a daemon that accepts the inbound connections, then compiles
the scripts a-la Apache::Registry, but puts each in a separate thread
would be, er, relatively easy for someone better at multithreaded stuff
than me.

In the X-Forwarded-For header. Not that you can be sure you're seeing
the true client IP anyway if they've gone through an ISP proxy beforehand.
