copied from my another thread post:
How can we sign a message by keyhotee?
PGP signature is fine. But it's hard to use. And don't it one of the reasons why you developed keyhotee?
Sign a message by bitcoin address is OK. But it's tricky, and not that direct. Also not easy enough.
To prove one's identity to another person by keyhotee is already easy, but not to the public. For example, you don't sign your keyhotee or protoshares-qt binary client, it's at least partially cuz it's not that easy, aren't you?
In addition, I think keyhotee need to have the feature, to send an unencrypted message to the public. Event bitcoin network can do that.
Keyhotee is new identity. And aren't these needed to face the future of identity?
