I've lately been looking around the options for foaf/openid integration. Having a foaf:openid property is the first little step. Also been playing with SPARQL for querying PGP-signed RDF data, where we have named graphs for the result of PGP-checking the RDF/XML doc. FWIW the proposed rdfs:domain of foaf:openid is foaf:Agent, so the possibility of non-human Agents authenticating is left open...
