Finally finished my webcam servo project. I'd been putting it back quite a lot but it's pretty much there I think. It's a combination of several techs: Arduino, Java, Linux Daemons, Apache, Python, mod_wsgi and HTTPS. Yup, it took quite a bit of work but its working quite well.
The next move would be to use Flash Media Server development edition and some kind of Air app but how that would talk with Serial devices I've no idea. Python saves the day on that one!
