I am really glad you guys (W3C) are paying attention to this space.

You did not mention the (Google) Social Graph API that is trying to  
create a navigable web of public "friend" data - this is being driven  
by Brad Fitzpatrick

The work that Drummond and company did around XRI/XDI was all about  
how to create a web of data WITH accesses control (privacy) built in.
This paper is actually the first use of the word "social web"

The think I am confused about when you propose this is that your  
browser becomes a "beacon" giving away your identifier to who ever  
asks.  Maybe I am not understanding  how this works but when Kingsley  
explained it to me at the Sem Web conference this is what I "got"

The identity community has gone to great lengths to articulate a  
vision for identifiers on the web that support citizens / people not  
giving away their identitifiers without their knowledge.

See Kim Cameron's Laws of Identity that are widely accepted with the  
community as sound basis' for these systems.
