Cheers, both --
Yes, exporting of baked models is supported, but I haven't had much success with it yet. Don't know what the problem is.
Animation export of your SU scene animations is also supported, although there's a bug in both Mac & Win. versions that stops scenes playing while recording. An update will fix this in the next week, hopefully.
My solution is just to play the LightUp-ed scene animation (they play really smoothly) and just record using a screen capture utility. Problem there is, your antialiasing is dependent on your graphics card. LU's own anims are exported with full antialiasing.
BTW, it's fully multi-core aware. Om my 8-core Mac Pro, that scene calculated in 4min 30 sec. with seven lightsources. After that it's real time!!!
Edit -- Gaieus Walkabout looks interesting...

... hah! that reminds me:
