Considering writing an #FEP that allows using #IndieAuth logins as display handles. The basic idea is that next to the meta tags/headers for OAuth links, you'd have a public key that can be used to verify a signature placed in a field in an AP Actor object. There would be another field next to the signature that tells remote servers what the preferred handle is. If lookup succeeds and the signature is valid, show the handle (possibly simplified) next to an IndieAuth icon.
