I think that is not a good idea to link processes in this case. You
better to create a master process called, let's say, "router" which will
route chat messages between processes. Also you can put some other stuff
in router - packet filtering, address rewriting etc. :)

Yes, that's a good idea. Also this approach will be "cluster transparent" for the router. But don't forget to delete state on processes terminating. That is simple to do via terminate/3 if you use gen_fsm behaviour for client processes.
