There was a Freemind Mindmap of extant bagua lineages at one point but due to annoyance by various people the author/compiler took it out of public webspace.
It resides on a private section of a server and has.. oh lord.. probably several hundred names at this point.
The problem is.. if you put something up in public.. half the people won't contribute to it, and the other half will complain about it somehow being innacurate (and they all disagree as to how).
