Just a quick update on my progress developing a shareable prototype. The basic integration work is functional, I've ripped out the previously-mentioned Camel workflow components in favor of ruote (which is so much easier to wrap my mind around -- I've pushed the skeleton code for this out as a separate package called fedora-workflow), and I've started doing some very basic datastream display work. After this work is complete, I think a first-round alpha will be ready to publish within the next couple weeks.
