Hi Zeno,
The EDI work is undergoing a rather major re-factoring and clean up at our end at the moment. Colin Campbell is doing the majority of the work and the unstable branch is currently in our private repository to prevent anyone accidentally using it whilst it's in such a fluid state. I'm hoping to post up the Version 2 patches reasonably soon, but please take this as a polite.. plese hold off an basing anything on that bug for now as things are about to change dramatically in there.
I've been quietly getting in touch with any parties I've become aware of who have been basing work atop it to prevent any clashes; I'm hoping that something can be shown/submitted during hackfest, though this hugely depends upon Colins current workload.
