[linux-elitists] wardriving without the driving

My 802.11b (WiFi for short) card came yesterday, so I decided to
pop it in and see if I had the right module to support it. Naturally
I had to change some stuff in /etc/pcmcia/config to identify the new
2.4 Orinoco driver:
class "network" module "orinoco_cs"
card "Lucent Technologies WaveLAN/IEEE Adapter"
manfid 0x0156, 0x0002
(should I be using class "wireless" ?)
but not only did the module turn out to be the right one for the card,
it also turns out that I have some generous, or clueless, neighbors.

Ooops, sorry folks, better put the card back in its box until I get to
some place with a WiFi net I'm allowed on.
Since WiFi's own security is kind of weak, I'm starting to think that
the residential gateway/webcache/nameserver/dhcp-server/etc device
should include something like one of those hotel Ethernet systems, where
it routes all your new connections to itself until you authenticate on
a web page. You could do it with a browser cookie, which would make for
rather painless web-surfing sessions if you did it right.
Or just never route the WiFi network out at all and make people do some
kind of tunneling to get out.
It would be fun to set up an anonymous WiFi-based Freenet dropbox
overlooking a crowded street or train station though. Walk through a
certain area with a node on a laptop in your backpack, and your stuff
gets out to the world.
