There's still a critical link missing, there's no way of proving in RDF 
that a person really holds the private key for which which they say they 
hold the public key.

If however one was to do something like sign their URI with their 
private key and pop the signature in the graph, then you could establish 
that they do or did hold that key simply by considering the RDF.

A few of us had a long conversation on #swig this morning, which starts 
off right at the above point, do see:

To save repeating it all,

Best,

Nathan
