Hello Gaetan, I'm one of the core developers of clojuredev, an open source project whose goal is to provide clojure support for the Eclipse IDE. What you say below is interesting, please see what I have noted inline -->

For mere mortals like me, could you explain the problem via an example ? (I understand there is a problem, I don't exactly understand what it really is) Concerning clojuredev, we provide clojure as a separate plugin, which exposes everything to plugins that depend on it. Currently, clojuredev plugin is successful in calling clojure core functions defined in clojure plugin, as well as loading new functions and namespaces from clojuredev plugin. > I > think the best solution is to use bundles class loader inside clojure > class loading system.

Is it possible for you to publish it, maybe via the EPL, which seems to be the 'defacto' Open source license to use when creating code around clojure ?
