Hope the Rhinoscripting is going good. I just sat through a presentation of Digital project. The program seems amazing and is totally compatible with visual basic, which is good for all of us that started learning. From what Nick Pisca said the plus of Digital Project is its stability, and of course real time parametric updating that rhino doesn't have. Also turns out a lot of other programs can be accessed through windows platform. I don't know the specifics of it but really its this real-time, network, cross-program workflow that is fascinating.
