Each object is exported explicitly in your code, and RMI is
thread-safe so to speak that its internals can handle multiple
incoming calls to the same exported object. It also means that your
code must be made thread-safe accordingly. If that is a problem, then
a typical setup would be that the main 'server' creates and exports
one object per session, which each client use explicitly. It is quite
ok to hand out a lot of exported objects to clients, as each client
JVM will try to minimize the use of sockets and interleaves multiple
conversations over the same socket (if possible).
