If I understand this correctly, it enables basic auth to one or more oauth based services for individual users.

The original intent of oauth was to provide a fairly simple way to authorize sites to access various portions of my content on another site, all without sharing credentials.

Any reason why you couldn't enable oauth to foauth.org, then proxy out to all the other APIs? I realize I could checkout and run this myself, but it seems handy for others given it was a bit more secure.
