Apparently this is an IETF draft. Do you know if it is stabilized enough that it won't change significantly?

Also, please notice that the ssl module (starting from Python 3.2) now exposes the notion of an SSL context. The setting of NPN parameters should probably be exposed as a context method and/or a parameter to SSLContext.wrap_socket().
(see http://docs.python.org/dev/library/ssl.html#ssl-contexts for docs)
