Like what?  Not let you use your network?  So then anybody who can
start up a "sniffer" can instantly blow away everyone else's ability to
use their network?  Cool <-sarcasm

Say what?  This would basically make all "sniffer" products worthless.
If I am trying to debug network problems by capturing packets, and my
presence on the net *changes* how the other machines are acting, then
it would be poor debugging tool, wouldn't it?

Except that there are myriad reasons why macs go "off air"...
