Yep, my bad. I guess I just tend to ignore any 'browser' information in

I guess I'm having a bit of difficulty trying to understand. Cookies
are local/stored on the user browser, correct? So with you in Los
Angeles and I in New York, we'll never see each others' cookies.
I interpreted your problem as essentially keeping a file 'open' or
'checked out' (insert your verb here) for 5 minutes before
allowing/disallowing changes or something. So, if you open a file at
10amPST, and I want to open it a minute later (1pm EST), I should see
that only 1 minute has passed (as opposed to 3 hours and 1 minute).
If that's the case, what I am suggesting is that when person A opens the
document, you record the SERVER time in a database or text file. Then
when person B hits the same document, PHP compares the time elapsed on
the server between when Person A and Person B accessed the document, ie:
whether or not its been less than / greater than 5 minutes.
Sorry to be of so little help!
