It would be great to have some sort of Steinberg media software, that can inspect an .cpr file and do an export without having to load the project.
other uses could be to have a look at what is inside the project - track names, region names, length, markers w/names, sample/bit rate, project notes, VST(I) errors, missing files highlighted, etc.
Obviously if there is real-time protocols (outboard mix) being utilized in the project, the .cpr inspector software would give a warning.
