http://poe.perl.org/?POE_Cookbook/Chat_Server seems to do what you want. =
 Whenever one client sends data, it's broadcast to all others.  It uses =
a shared hash to register clients and a global helper function to =
iterate the hash and broadcast messages.

Of course your version of broadcast() can do more complex calculations =
and determine which other clients will receive the results.  Your shared =
hash can also contain a lot more information for each client.  And since =
it's shared, any client can inspect it at will... without pesky message =
passing among clients.

If a shared hash and accessor functions doesn't feel right, consider =
abstracting it into a singleton class or object, and give every client =
the package name or instance to the object.

I think this covers all your other questions.  Please let us know if it =
doesn't.

Thanks!
