I am sorry to hear about his leaving ... but in the end nothing about the magnet sets or the way they are controlled IS actually somehting he can keep as intellectual property. It is not a copyrightable concept. It is not a patentable concept. (well, he might get a patent, but it woudln;t stand up to a challenge). Just like when one person figured out MAT and MOR files others don't have to pay them for that priviledge... once these magnet sets are out "in the wild" there is really nothing protecting them from someone else reverse engineering the process. It's a sad reality - but it IS a reality. It has nothign to do with these hacks and the people who made Poser... it has much more to do with the basic premise of what is and isn't a protectable concept.
