Python came out in 1991 but occam in 1983....
As it says in the article there is only a Mac version at the moment, with windows and linux versions coming out for OSCON. If you are using Linux building it yourself is quite trivial. We know the naming is confusing, and I agree a plugin for the arduino IDE would be nice.
I don't think so, Occam is based on CSP algebra, wikipidea has a reasonable description of the language http://en.wikipedia.org/wiki/Occam_programming_language

Now a group of academics have ported the parallel-processing language Occam to the Arduino. In an interview on O'Reilly Answers, Matt Jadud of Allegheny College describes how Occam helps artists using the Arduino in their installations, and how the advent of low-cost computing platforms is changing the educational experience for proto-makers in school. 'Basically, an artist or a tinkerer or a hacker has a goal. They don't really care about learning Occam. They don't care about how this language is different from C. They just want to make a cat door that keeps their cat out when the cat comes back with a mouse. Or they want to make some kind of installation piece. Trying to focus as much on the user and the possible goals they might have is what's motivating our work right now.'"
