It has been aggressively marketed, does that count? It is essentially, IMHO, a sales funnel into data science consulting services. They have some demo interactive things you can play with, but the real deal is a whole suite of ML techniques that they've either already made or can custom tailor to your needs. It is managed I believe by Apache UIMA. But if you already are doing this stuff, you may have a leg up in house.

Anyway... so you could probably think of it as you might think of web development solutions, that is, there isn't one thing, but a suite of all kinds of things, and that IMHO is Watson today. I think they have a big gaping cloud offering as well to run those models they have or come up with as well, but it isn't like Watson is this single computer that won Jeopardy, and that exact computer they are now letting everyone use or something... I mean it is, but it also isn't.

Yes. We have a bunch of cloud services (including visual recognition - demonstrated here) that you can embed in your own application. Try them here: http://ibm.com/watsondevelopercloud

Yeah, they've got a cookbook out. http://www.amazon.com/gp/product/149262571X

They are using it to create a pretty impressive system that provides oncology treatment recommendations. I saw a live demo.
