Push Technology : Is there any open source implementation for windows

Question

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 ?

Are u looking for an API for a open source server product. What your usage. There is a few open source push engines, but they are categorized, so some push docs etc, others push calender, task via IMAP, and so on. What do you plan to push. — scope_creep, Mar 14 '10 at 21:01

Orbited
Orbited is an HTTP daemon that is optimized for long-lasting comet connections. It is designed to be easily integrated with new and existing applications. Orbited allows you to write real-time web applications, such as a chat room or instant messaging client, without using any external plugins like Flash or Java.

It can be installed as a windows service. The license is MIT.

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.

Lightstreamer
LightStreamer Moderato is free but not open source

WebSync
WebSync is a standards-compliant scalable Comet server for IIS using .NET. It's also available on demand as a hosted service. This is neither free nor Open Source, but does have a free trial.

Other
There are several more Open Source Comet projects:

aspcomet The aim of this project is to develop a COMET implementation which does not require a custom server, but can run in native IIS.
emerge toolkit. No project activity in quite some time.

If I use orbited or MethodWorx in my application, does my hosting server need to provide additional resources, like any additional server or windows service etc. ? — MD Sayem Ahmed, Mar 30 '10 at 13:12
@Sayem orbitd is a windows service, MethodWorx is part of your ASP.NET website — Lachlan Roche, Mar 30 '10 at 23:05
looks like methodworx is down as I checked it today, any new updates on this list? — Aivan Monceller, Mar 08 '11 at 22:48
FYI, WebSync has a free version with concurrency limits, and has been updated to support WebSockets now as well. — Jerod Venema, Jun 25 '12 at 12:57
