[OpenGuides-Dev] authentication modules?

hello,

i'm wondering if anyone has developed, or is working on, an authentication module for OG.

briefly, i set up an OG for some collaborators; they're now threatening to switch to a different wiki, and make the existing one read-only, because the spam problem is so bad.

the time/energy i want to devote to fixing this, is minimal. if anyone else is at least halfway, i'd appreciate a peek at code; i know it wouldn't be too much effort to hack something together, but it would be pretty thankless (though i suppose it's something that a lot of people want? trivial 'are you human', cookie-based spam holdoffs have simply not worked... and i know we went through that debate a few months ago...)
