Comet for web

With the move of our application to the web - we have to achieve the same level of interactivity that people expected from a desktop app in the new web app. To achieve this - there are some very clever things you can do in order to do this. We are experimenting with comet technology - a long poll from the browser that is light weight enough and if designed properly in the server doesn't use a lot of server resources. This long poll allows us to push stuff from the server to the client very effectively. Pretty neat and also interesting to see the creativity that people have in making things work the way they were never intended.
