I haven’t installed Medley, but I watched your video and man I loved it! It just made me remember why I love Lisps and how revolutionary they were and still are. Surely there are a lot of ideas to learn from that environment.
Glad you enjoyed it, installation honestly has been a very easy experience for me on Ubuntu Loonix. :) Since it's image based you can just pass out your image and be done with it. I'm not sure if Mac and Windows folks have been able to run the image since it was created on Linux...
