To me this sounds super-interesting - I would love to see this work!
@DrCWO: I found a download-link on your website (at least I think it is yours) and booted one of my RaspberryPis with that image.
Not surprisingly, though, access to the system is password-protected. Do you want to keep it that way for the moment or would you be interested in another beta-tester? If so, I would gladly volunteer …
But anyway: Congratulations on this excellent idea!
