There is a new addon landing. If you work with IBL in Blender for modeling come by soon. In the mean time enjoy the teaser (or poke me to provide some feedback and perhaps even join the alpha testing period).
IBL autosetup for Cycles and Luxrender
IBL Re-Aligment
Home made panoramas also work š
Point projection for calibration tweaking
