How to create a facebook like tickr?
===

I am working on GPS tracking web application which shows information on various features like position,speed, heading towards and the image files recieved from his Mobile device. To make it more interactive I want to create a page called timeline which can show the updates in a auto-refreshing div like
1) USer-1 just uploaded a video
2) user2 has reached Texas at 12:00:34.
etc...


How can i make it.. i am not asking for code. Just want some verbal help and a little guidance.
Also i searched for the same on internet, but all the examples are in php and what i need is an example or reference in ASP.net. Please Help.!
