No, each client only connects to a single daemon. That daemon then acts
as the client's "representative" within the communication system and
performs the necessary actions to serve the client's needs.
A client's connection can either be to a "local" daemon on the same
machine using Inter Process Communicaiton, or it can be to a "remote"
daemon on another machine using TCP/IP. If the client's connection is
local, then the client-daemon communication remains within the machine --
no network bandwidth is consumed. If the client's connection is remote,
then the client-daemon communication goes over the network.

Yes, when you place multiple daemons within the same configuration file
(e.g. - spread.conf), then those daemons will work together to form a
distributed communication system. Clients that then connect to any of
those daemons will have access to the clients connected to all the
currently connected daemons in that configuration.
