To what degree depends on your network speed I guess. You can also use stream pipes, which also give better (allegedly) performance than network. The idea of using network connections is one of security. Most competant C programmers can 'hack' into a shared memory segment, or so I am told. It is a little more difficult to 'hack' a tcp packet. :-) Hope that helps, -- Mark. +-------------------------------------------------------------------------+ |Mark D.
