Crytek has published a new paper & presentation on their website of some new technology they are working on for CryEngine3: Real time computation of indirect illumination. From the description:
This I3D 2010 paper is a result of collaborative research with Carsten Dachsbacher. The LPV technique was extended to support secondary occlusion and multiple bounces. The propagation scheme is improved and compared to similar Discrete Ordinate Methods. Also this paper describes many additional application and implementation details.
They’ve published the Paper & Powerpoint slides online:

Simply Amazing.
Their oclusion solution is very coarse but very simple. I was expecting the implementation of inperfect shadow maps, but what they did seams to riquire less comuptation and memory
