I have read about the push technologies recently. Using it real-time data streaming is very easy. I also saw an implementation called ajax push engine, but it runs on linux or mac server. I wanted to use this technology in an asp.net site.
So is there any open source implementation of the push technology that is available for direct use on windows platform ?

MethodWorx
MethodWorx was developed out of this series of articles on Code Project. It has an Open Source license.
This is a packaged version of a library the we used in some projects to enable COMET polling or Long-Polling within some of our ASP.NET applications.
It uses an Asynchronous HTTP handler to keep ASP.NET connections open to wait for events to occur, enabling real-time AJAX callbacks.
