I think we may want the server to send something on the 'r'esult channel,
(like 'ready' or something), once it finished sending the hello message.

This way we can add more stuff to the hello message in the future
without breaking old clients. Clients will then treat everything on the 'o'
channel sent by the server from the moment it starts to the moment it
sends the 'ready' signal as the hello message.
