Unless you generate more than one WWN per second. We could enforce that by have an msleep(1000) in the WWN generator function ... which might discourage people from using it except when they really had to ;-) Of course, if you turn on two computers in the same zone at the same time, you're still screwed. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
