I don't understand the question. How is that input produced? How shall the two processes interact? Through some logfile one writes, the other reads? Through RPC-mechanisms? Sockets? Pipes? The fact that process B is a daemon or not has nothing to do with this whatsoever, btw. Diez -- http://mail.python.org/mailman/listinfo/python-list
