Hey thanks for tracking this down! You learn something every day.

Yeah I know the limitations :-) They might even get a new IP address  
for each request within a single session :-) I'm not really worried  
about that kind of security for this application. It's a wiki-like  
system... I just want a way for users to be able to tell whether a  
sequence of edits all come from the same (unregistered) user. Since  
that's theoretically impossible, the IP address provides the best  
approximation for the least work that I can think of right now. It's  
not that important anyway, this is all just proof-of-concept for now.  
(The system will of course use session cookies, not  IP address, to  
track *session* data.)

Thanks for your help!
