I built it using OpenLaszlo instead of Adobe Flash tools since I don’t own a remotely recent version of the Flash software and I wasn’t going to spend $700 on getting it. So I did a little research and found an OpenSource option. It’s a little wonky but it did the trick.
Now I just need to find a way to get the Silverlight player to work on the Chumby. I wonder if anyone is working on a Linux Arm build of the player?
