I think I understand the objectives but I don't think I understand the 
approach, or rather I don't see how the proposed project can explore 
interoperability without experimenting with changes to some OSGi 
implementation. As an initial step I would expect some changes so that 
the OSGi implementation will install and run in module mode. I would 
also expect changes so that the OSGi kernel can resolve modules that are 
installed in a Jigsaw module library. If changes are required then would 
these be in another project? I've no doubt that this effort will require 
changes to Jigsaw too, in particular the API, but not clear me that the 
goals are achievable with only changes to Jigsaw.
