Or, easements for WiFi.

I can use a wireless access point for one of two purposes. I can place it inside my (home or corporate) intranet and make it secure. Or I can place it outside my intranet, and broadcast its presence to WAR drivers. But I can’t do both.

[Actually, I can’t do the first, because WEP isn’t secure. But WPA will fix this problem, and it won’t fix the other one.]

Wireless access points should come with a setting that permits public access through them to the internet, but only secure access to the intranet they’re serving.
