What you refer to as Truth Oracles I see as a form of Notarization Service. An interesting point regarding the law in the US  at least, is that an Affidavit signed by two Witnesses testifying that we are who we say we are and that we signed a document in theory presence has the same legal standing as if it had been Witnessed by a State licensed Notary.

This seems a perhaps relevant precedent to model for the CivKit ID service. The security protocols from the Paper realm won't entirely translate to the Digital centralized and Virtual decentralized realms, but some protocols are worth considering and perhaps modifying as appropriate for each phase state of our data.
