That's great, but there are a lot of libraries to make consuming oauth services easier. I'm more interested in a good library for hosting them. I use Python and have yet to find a single unified framework for serving Oauth both two-legged and three-legged, so you can use the two-legged with your in house apps. Everything I've found is either three-legged or one-legged.
Interesting, but I hope there is clear direction to never use 1 legged OAuth in production. Because that's a bad time.
