cool ;).

sound good

maybe I'm wrong but AFAIK the idea of the api project was to host the 
new jcr api and not jackrabbit specific interfaces. However I think it 
would be a good idea to move the internal interfaces into one or more 
separate packages and reduce the dependencies. I'd like to see the 
jackrabbit core components not only as the RI but also like a modular 
and extensible toolkit for building custom jcr implementations.
