Hah, no that's pretty much true I think. I've got an old Intel Core Duo iMac in the closet that I use as a home server. The Time Capsule router logs everything to the iMac's syslogd and I've got some scripts setup that will alert me (and flash the
Blink1 on my MacBook Air) when a new MAC address appears on the network.
So I feel I've got a pretty good handle on my network. Good password, WPA2, I'm not really worried.
