This is a design issue I've been wrestling with. One way to do it is
have a method on the factory that the protocol calls in connectionMade
with itself, and then the logic for sending commands to the client is in
the factory.

Another solution is t.i.protocol.ClientCreator, that lets you get back a
Deferred of the protocol instance.

Any other solutions that people have found? I'd like to be able to make
a single, canonical clean way for doing this.
