I can tell you from what I've seen of the Face Room files (under Runtime->heads) that they are not editable like CR2 files. The XML file registers the P5 figures with keys. How those keys are determined is not mentioned anywhere. The PH5 files are binary (possibly just encrypted), so it would require a knowledge of what format they represent which could be proprietary. I agree that if anyone is working on cracking this one, it will take some time because of these binary files. Maybe some inside info will get out about how this all works. ;)
