I'd love to see a "RAW Development" space where RAW files can be shared and developed by folks using any RAW files utilizing any editing software. This is a great way to help folks with specific RAW editing issues, and where anyone can share a RAW file to compare and contrast whatever results they're getting with what can be accomplished by more experienced folks using their own, or whatever software is out there - a great way for anyone looking to hone their post processing craft with the big benefit of having others' examples for reference.
PIXLS.US has such a space (RAW PLAY), but with participation limited only to folks with open source software. discuss.pixls.us/c/processing/playraw/30
