Well, OpenBSD isn't everyone and yes, I do remember reading that discussion when LDP started.
I could imagine some FreeBSD developers would be interested, maybe the primary thing would be
to get access to the documentation by signing a NDA. I would think having a company handle the
legalese would be nice. Also, even though they would be developing for different platforms
(Linux and FreeBSD), they could probably learn something from each other or help each other
out understanding the documentation.
