WebID is existing technology. It essence is:

1. URI based Names
2. URL based Data Access Addresses
3. Graph based Data Representation
4. Data Access Logic for determining Who can do what from what Address.

We are dogfooding the very technology we want people to use. We are 
applying it to a serious and unavoidable problem.
