I implemented a friendship model like Flickr's where you can have a friend that doesn't call you a friend... I used Josh Susser's self-referential model (http://blog.hasmanythrough.com/articles/2006/04/21...). I want to change to the myspace model where two people are either both friends, or not at all. Are there any examples out there that implement it this way?

There is an example of such self-referential joins and rules in Fowler's "Rails Recipes."
