1. So the minimalist consumer I decided to scrap. It's still a bit PHP4-ish, which isn't bad, but didn't help it's case any

But the fact that it was simply "free" for use and didn't have a license made me want to stay away. So I wrote my own which is similar in that it's simple and CURL based, but mine actually lacks the SREG functionality that this library did. I figure I can add that later, I just want authentication at the moment.
2. The lib will identify if someone is a certain openID_url if they are it will let you run a callback function. That callback function can take care of whatever your app requires in order to either 1. add that user to your system or 2. have them go through a registration system. For example on reviewsby.us I have them automatically get a profile if they use openID. I also happen to be using sfGuardUser which stores the openID as their username for login.
3. Definitely, I cleaned up the code this last weekend, and I plan on uploading it to the wiki this week... although I'm a tad sick, so it might take til next week.
I'll comment here once it's up, and I know there'll be problems with it, at least documentation wise... so we can hash those out until the library is worthy
