"Push" linq vs reactive framework

Question

(Once again exposing the depths of my ignorance here by combining two concepts which I haven't grokked)

I read here about the Reactive framework being a 'Push' model compared to Linq's 'Pull' model. This reminded me of reading an article about 'Push' Linq.

Is there really any similarity between these two 'frameworks'?

UPDATE

Since I asked this question, Jon Skeet has asked it too, here are his first and second impressions.

Answer 1

Yes. They both give a method of how use linq operators on streaming data.

The Reactive Framework is likely to have wider adoptions.

• I has a nice logical clarity to it. The opposite of IEnumerable (pull) can be expressed as it's dual in IObservable (push)
• It'll be baked into .Net 4
