Either that or an escrow house/arbiter has to just come out and say "hey, this is who I really am" so there is recourse in the event of fraud.  I'm working on something along these lines, slowly and surely, where my real information will be posted as well as arbitration clauses involving judge.me (which are enforceable in court - hence they only have a <4% default rate).

For now, until a system of checks and balances can be put in place that supersedes traditional escrow, somebody is going to have to forgo the anonymous armor that bitcoin provides, and that someone is going to be the escrow house.
