The question is old and the technology has advanced, here is the current state:

JSON Web Token (JWT) is a JSON-based open standard (RFC 7519) for passing claims between parties in web application environment. The tokens are designed to be compact, URL-safe and usable especially in web browser single sign-on (SSO) context.
