Is a group that aims to build 50 machines that are 1) "hand-build" and 2) way way cheaper then industrially build ones. In short: the mustachian do-it-yourself version of the tools you need to have a functioning village, which is why they called it "Global Village Construction Set".
All the plans will be open source.
The FIREd (or just starting) mustachian could learn a lot there, for example how to build a house with your own hands. MMM himself would surely like the "house work"

http://opensourceecology.orghttp://opensourceecology.de/Perhaps there is a FIREd mustachian out here who wants to have a little go in making and selling/renting these machines to other mustachians?
