needs the API to exist in the language that you want to write analysers 
in.

makes the API into a posix filesystem with text files. still needs a 
per-language parser to parse that format, but that is 'simple' and works 
in a variety of languages. so I'd favour this.

Possibly some components can output stuff into a common format using log4j 
- that wouldn't necessarily be any more dynamic than the existing log4j 
output.
