noaccess int optional Set to '1' if access was denied.
challenge bin optional 32 bytes of random challenge to be used in next authentication request from client.
Always present if 'noaccess' is set. This is supplied so the client does not have
to issue an extra 'getChallenge' request.
}}}

=== setAsync ===

Switch the session into asynchronous mode.
When a session is in this mode the client will get continuous updates from the server about channels and tags.
This also includes creation and deletion of channels and tags.

An interactive application that presents the user with information about channels and tags would probably want to switch to this mode.
