Thanks for all the responses ;) I updated the FAQ with more details 
based on this. If it's incorrect please go edit.

I'll stop flooding the FAQ in another hour or two. I hope it's a good 
enough start to motivate other folks into undoing my damage. It's time 
I spent more time writing code elsewhere :)

I'm sure the OSCON BoF might produce plenty more interesting details for 
the wiki (which unfortunately I missed this year). Someone should 
check/post!
