You can't build "real" CF instant messaging app with pure Coldfusion, because CF apps work on top HTTP request/response model. You can't push data to the client.
You'll need a client able to open a constant connection to the server, which require a special clients (java applet, flash player...) and a special server (socket server). If necessary, you can simulate a kind of instant messaging by using the CF application scope on the server side, and check each time a client make a request to see if it has pending messages, but if the client stop to make request, it will never receive any messages... It is exactly the same problem when you try to build a chat application with CF. Usually, you put a javascript "refresh" command in the HTML page to check every x seconds to get new content from the server, but this definitely not an elegant solution (even if the "reload and check" page is hidden in a one pixel page in a frameset ;). The other issue : you'll never be able to know when the client close the browser (because most of the time, people don't use the "Logout" button that we put to try to solve this problem...). Again, the work around would be to put a javascript "onClose" command that open a pop-up to execute a deconnection script on the server... A lot of work arounds for a pretty bad result. The best instant messaging app would be Flash Communication Server with a Flash MX client. It is very easy to build with the new Flash Communication Components, but it requires a FlashCom license...
