Does such a thing exist? If not it's a fascinating idea.. I spend a lot of time tweaking/test rendering shaders to get them dialed into the photo-real area, when all of this data is based on actual math... Seems to me that something like that should already exist, but I haven't been able to find it. MERL (http://www.merl.com/brdf/)has something, but i haven't been able to get access to it and see what it actually is and is not..
