Websync or Comet or Reverse Ajax or JQuery Expert Needed

I have a project that sends out data using httprequests, and a webpage that displays this data using a refresh of every 3 seconds. I would like to get rid of this refresh and slower httpreuests and use a better push technology. The data that needs to be sent is from a c# application to a web application(ASP.net, C#). The interface is connected by a c# web module that contains the info and http requests. I will provide a demo to qualified interested parties. I can NOT provide the source code here. All work must be done using Teamviewer. The demo will be shown using teamviewer as well. I am using visual studio 2010. The project is currently all set up and working properly. The problem with what im currently using is that if data is sent to fast and the client browsers are in the process of refreshing they might miss some data.
