Thanks for the posts, I'm going to try using the onbeforeunload method, it seems to have support in most recent browsers. I'd if it works it seems less error prone than a polling system.
Is it possible to call methods on one of my tapestry page's methods from a piece of custom javascript? Thanks also for the pointers on the system design, this is really just a simple tech demo to play with tapestry at the moment so I'm not too concerned with how it all hangs together.
