I don't believe it works in practice. I remember CableCARDs and Tivo, what a disaster that was. Comcast came to my house 3 times and never got the CableCARD to work right, so I gave up and just took their DVR. I imagine an interoperable API would have all sorts of problems, bugs, timeouts, etc. and the company would just claim they are doing what the law requires.
