Interesting DNS hack to get free internet from any for-pay airport / wifi hotspot
The Idea is to tunnel all outgoing traffic through DNS. Yes, you heard right, through DNS, the Domain Name System, used to translate human-readable hostnames to numerical IP addresses and vice versa.

Pretty interesting/novel way... Unix admin skills required, but it's probably better that way.
Luckily I don't ever have to worry about this anymore -- I pretty much just use my Sprint 3G USB modem when I'm out and about.

Another implementation of the same idea (done by a friend and colleague of mine) is DNScat: http://tadek.pietraszek.org/projects/DNScat/

I tried this out one time at the airport when I was in college. However, as far as I could tell from Ethereal, the DNS requests never escaped the airport network.
