Since I am a happy FreeBSD user too, I wanted to use it on my favourite OS. Thats why I started to investigate some issues I had on this plan. Most of the trouble was related to the Java 3D native libs and a conflict with FreeBSDs Linux emulation. At the end I created a native FreeBSD port which is currently waiting for beeing committed to the ports tree.
For those of you who may be interested, I want to share my findings:

I'm also looking forward for feedback. The port is the first version and I am sure there is some potential for optimization.
Kind regards,
Matthias
