Interesting. I will have to look into it more when I have a bit of time. (Anybody know where I can pick up a six-pack -- or better yet a case -- of extra hours?)
For those Yun users who don't want to lose the Bridge functionality, is there any reason the Python code couldn't just read from STDIN and write to STDOUT instead of opening ttyATH0? That way, the Python code could be started using a Process object. (Do realize that I haven't looked at the code yet, just the doc.)
