RPG.net user thecosmicgoose has extracted the OGL bits from The Kerberos Club (FATE Edition) and made a system-reference document out of it. Now, admittedly, it's basically two chapters from the book with all the non-OGL stuff excised, so it's not exactly pretty, but hey, what do you want? No doubt the it'll be subject to some prettification later, and by someone other than me, because man, I do not know what I'm doing on that front.
Anyway, the SRD is here. Check it out and have at it!
