Heh...
Just downloaded (and purchased) something called OpenVPN, from WiTopia. It's a program that creates a VPN (virtual private network). It's used to secure your wireless connection at any free hotspot. Basically, it creates a direct connection between your wireless computer and their encrypted system.
I remembered this thread and came here to test it.
Without OpenVPN running the sign in the pic reads "I Luv Toronto". I click on it, and it changes to "I Luv Washington". Very cool.

That means it's working (and it's changing my IP address).
