You should probably have two segments corresponding to the two separate
networks -- assuming that by "networks" you mean that machines within
these "networks" can 1 hop broadcast or multicast to each another.

You should run the daemons on machines whose IP addresses are accessible
(i.e. - routable) by all other daemons in the config file. So the
daemons should be run on machines in those networks that can reach the
daemons on the other network.

This is up to you. But generally you should run at least one daemon per
network that will have clients and usually even run 1 daemon on each
machine that will have clients. You run more daemons both for network
efficiency and for fault tolerance.
> 4) To which daemon should each machine connect to?
Each machine should connect to the closest daemon that it can. Usually,
this is often a connection to a daemon on the same local machine.
However, since it seems your client machines will be on private networks
that would not be routable by all daemons, you will probably need to
remotely connect to the closest daemon with a public IP.
