What commercial or homebrew systems are available to generate a full hdri environment map on set? Often there is not much time to acquire the data, so a system which automatically takes lots of pictures at different exposures and ideally stitches them together / combines them into an hdri for later editing would be great. Does anyone have good suggestions?

The main system I know of is HDR-Cam.
It gives good pre-stitched HDR environments. Occasionally the procedural stitching is not 100% but for IBL and general environment work I thought the images were great. I don't have experience with it on-set and apparently early models were quite bulky, but the images on the website look quite practical. Little more than a box on a tripod. The website quotes capture times at "about 30 seconds".
You might also want to look at SpheroCam.
I don't have any experience with SpheroCam images but I know it gets some use. Apparently it does the same thing; pre-stitched HDRI. Speed-wise the website says between 60 seconds and 30 minutes, which would make it difficult (and unpredictable) to use on-set.
