Well, its not really possible to have the server initiate contact with
the client. So, anything you do would have to communicate between the
two browser windows on your local machine (the same way emacs works).
I suppose this wouldn't be to hard to do in FireFox - especially if
you are using 2 tabs in the same browser window. But then again, a
browser extension may be a little much for this. Don't know if a
bookmarklet would accomplish the same thing.

Another option would be to have some autorefresh code in JavaScript,
but have it do an Ajax request to check with the server whether the
page has been changed before reloading, or something like that. Again,
it has to be initiated on the client side - not from the server. Then
you also need the server code to respond to the Ajax request -
probably more work than it is worth.

Either way try Googling for "javscript autorefresh" or some such and
you should find plenty if code examples to get you started.
