/* in the Application.cfm */

// if user's last access is older than their session timeout, remove them
if (dateCompare(application.user[u], dateAdd('n', -20, now()), 'n') lt 1) {

This is only to illustrate the concept, you'll want to do some heavy editing
before you use it: Locking, copying to local vars for display, etc. are all
things to consider. I have no idea the number of users you expect, etc. so
you'll have to decide if this is right for you.

Not sure I fully understand - could you show me an example bit of code? I'm
still not familiar with structures.
