Simple example, how do I express the following:

1. you can only sign up if you are no greater than 1 degree of 
separation from TimBL, in a social network
2. you can only access a resource if you are known by TimBL
3. you can alter (e.g. extend membership) a resource ACL rule if you 
claim to know TimBL and he also claims to know you.

Those rules are just the elementary level stuff. I can assure you that 
there are no OAuth solutions in the Web 2.0 realm that can handle that, 
let alone the kind of dexterity that Linked Data, WebID, and the SPARQL 
protocol bring to the table re. ACLs and data access policies :-)
