Are there any free engines that support physically based lighting?

Some of the recent conversation in the UE3 thread has centered around physically based rendering for games, this is really a topic that deserves it thread so here we go!
First, some links:
Image based lighting, which is essential for a PBR workflow - Paul Debevec, Debevec's research is probably the basis for most IBL implementations out there today: http://www.pauldebevec.com/Research/IBL/
Adopting a physically based shading model (mostly math) by Sebastien Lagarde: http://seblagarde.wordpress.com/tag/physically-based-rendering/

Kodde's PBR Maya shader: http://www.polycount.com/forum/showthread.php?p=1505129
Let me know if anyone else has good resources and I'll link them here as well.
I've pulled some posts out of the UE3 thread, and combined them in this thread, so some comments may look a little confusing.
(Sorry zac, since this is the oldest post it will always be up top, hence the editing)

I would like to get a head start on learning how to create assests for physically based lighting, since is seems like many major next gen games are going to start focusing on it.
