I've been using SSO for years using an X.509 private key in my browser, and
my public key referenced in my home page.
The unfortunate thing is that X.509 tends to use RSA, and bitcoin tends to
use ECC for space reasons. Since, in its simplest form, bitcoin is a
distributed ledger of public key / balance values you could imagine an
enormous eco system where every key pair become a wallet with 10s of
millions of users.
I was thinking about an alt coin along these lines. The problem is that
there's no OP_CODE for RSA and the block chain would become massive.

Sounds great, would love to hear more about what you come up with!
