Right, sorry, it runs on Windows, i.e. on your PC, not on your Edge. What it does is synchronise all your Edge Journals with OneNote on your PC. Currently you still have to use hand writing recognition manually on the PC, but I'm working on a version that does the interpretation at synchronisation time.
So, it is not an extension to your Edge Journal - that's what I had in mind first, but Entourage does not publish the SDK for the eInk side...
