The term "mission critical" itself can have a wide range of connotations. If a software failure would force a military pilot to abort his mission and hobble back home with a partially disabled aircraft, that's what I think of as "mission critical" software. If Google needs reliable software on its servers to maintain its revenue stream, that's another kind of "mission critical" software, but the criticality is certainly less immediate in that case. In the first case, the software glitch definitely causes mission failure. In the Google case, the software problems *may* ultimately cause mission failure, but probably only if nothing is done for quite some time to rectify the situation. If that is the case, then the software itself is not the critical factor unless it cannot be corrected and made to function properly in a reasonable amount of time. -- http://mail.python.org/mailman/listinfo/python-list
