ok, we got webstart going for Linux and Macs. Need someone to test though.

Webstart doesn't seem to want to start with Safari, but Internet Explorer on Mac handles it fine. Anyone know why?
EDIT: Seems there is an issue on the Mac, textures aren't loaded so objects just appear black. For example, if you run the MD2 test, you'll just see a black outline of the model animating. Investigating.
