At least using the Installer, we can have separate install paths to use or not use PB shaders based on the FP/AIR versions the user selects. > > Also, I'm not sure how much work it really is.

I think it is too much effort for a few shaders. IMO, we should compile the pbk files and keep the binaries around till there is a need to change them.
