People that know me can confirm I'm a promotor of "Free internet⁽¹⁾ everywhere".
I don't hide the fact that I regularly use someone else's wireless network/internet when I need it and I'm not home. When doing this I'm of course following the ethical guidelines related to this.

I have myself opened the wireless connection at my parents place for quite some time now. Of course this can be considered unsecure, but almost every connection that has passwords in it uses SSL (or similar).
Once my internet connection at my new place will be up'n'running I'll provide free internet to a few houses. Considering this I thought it'd be a good idea to finally activate that disclaimer-page on my Linksys WRT54GL box running DD-WRT. The access point and SSID is currently called portunes (related to Roman mythology), but the SSID will soon be renamed to "free-internet portunes" to make it more clear to people they can use the network.

Well, the welcome-page can be found here: http://portunes.vandeplas.com/

Feel free to open your own wireless and contribute to free wifi everywhere !

(1) Free internet is not the right term. Everyone that uses someone else's open wifi should also open his own internet. This means you still pay for your internet...but yes, the difference is that you pay for internet -everywhere- and not only internet -at your home-
