I've been fighting with this problem for two days now, and don't have a solution built yet. But your answer has helped me stop looking in the wrong places! Now I can go try to find a simple "COMET" solution to my problem with posting back to a client from the server. Thank you! – Scrooge

PokeIn gives you an enhanced JSON functionality to make your server side objects available in client side. Simply, it is a Reverse Ajax library which makes it easy to call JavaScript functions from C#/VB.NET and to call C#/VB.NET functions from JavaScript. It has numerous features like event ordering, resource management, exception handling, marshaling, Ajax upload control, mono compatibility, WCF & .NET Remoting integration and scalable server push.

There is a free community license option for this library and the licensing option is quite cost effective in comparison to others.

There is a free edition of Lightstreamer - you'd have to look at the feature list though. http://www.lightstreamer.com/products.htm
