I'm posting this for anyone else wondering. After much hair-pulling I was able to get Lightjams outputting to my Velleman VM116 over ArtNET using the artNET to DMX app that comes with Freestyler. Presumably you could do the same with any usb interface that freestyler supports. Anyways my 2 cents, hope it helps someone.

Cheers!
