I've been looking at ways to implement gmail-like messaging inside a browser, and arrived at the Comet concept. However, I haven't been able to find a good .NET implementation that allows me to do this within IIS (our application is written in ASP.NET 2.0).

The solutions I found (or could think of, for that matter) require leaving a running thread per user - so that it could return a response to him once he gets a message. This doesn't scale at all, of course.

So my question is - do you know of an ASP.NET implementation for Comet that works in a different way? Is that even possible with IIS?

Comet is challenging to scale with IIS because of comet's persistent connectivity, but there is a team looking at Comet scenarios now. Also look at Aaron Lerch's blog as I believe he's done some early Comet work in ASP.NET.
