Well, the listed `rwt' function isn't used any more.  I've not  
interested enough to read the full source of a search result, but  
presumably all I need to do to verify this is perform a search  
followed by a result-click from my office machine (no NAT, RFC1918,  
squid proxy) and then grep my IP number out of the squid logs?
