>Interesting. What is the distinction between a LAN application and an INTRAnet application?
Is it that an INTRAnet application uses a browser interface?

Yes, but for an INTRAnet the web server sits internally, and is only used internally. That way you are hitting the web server at 100 MBPS (or 1000 if you are running gig), instead of 3 MBPS on common cable broadband.
