My read of the protocol docs from when they came out a few days ago is that they're using Blockchain in the distributed merkel-tree ledger sense and not (explicitly?) in the sense of a cryptocurrency.

Unless they plan to add a namecoinish thing for identities you shouldn't really need Po* to "secure" that.
