I didn't read the articles because of time, but I wanted to comment on the registry project.
It's incredible that you managed to compile so much data, but it seems pointless because that data would be changing all the time. If I may suggest an improvement:
it would be good if the website was wiki-like in nature, so that fans can make their own entries, and you could just edit if necessary. Also, some sort of rating scale of fan designs would be a good idea, so that people can see top designs and not some ugly duckling which, in my opinion, is what most fan designs are. Even some video game designs are so ugly and even bad from an engineering point of view, I don't want to waste my time on them.
