You cannot get the client IP directly in Rugby. The ports are stored in
the i/o engine (port-q and object-q), but you cannot see that when a
function is invoked (you don't see what client is calling).
You restrict access to a set of functions using the /restirct
refinement, but I doubt that is what you want. Perhaps a simple
private/public key scheme works best here. With all the spoofing going
on that is a better idea anyway.
