Is the Reactive framework available for .NET Framework 3.5?

Question

IObservable and IObserver would be quite handy right now for something I'm working on.

Is there a similar set of interfaces and classes available for .NET 3.5?

Or must I wait for .NET 4.0 before I can use them?

This blog post -- Rebasing System.Reactive to the .NET CLR -- explains how you can get the .dll from Silverlight Toolkit to work with .NET 3.5. Don't miss the update at the end (and the comments).
