1. Without receiving data
This is simple. When a client connects, your protocol can capture
the connection event with connectionMade method on the protocol.
That's when you'll likely store a reference to the protocol instance
on the factory. If you need to write back to the connection at a
later time, simply call write on the protocol's transport. For
example, a chat server might do something like this:
for c in self.chatters:
I'm guessing that your concern is that write is going to block. It's not.
2. Client connecting
The client has to connect first - unless you are writing an
application where each participant in the system is known up front -
and you can establish connections with them (no firewalls).
I would suggest rereading these documents carefully - they should
really cover your questions:
Otherwise, you should provide a more detailed explanation of your use case.
