Be your own WiFi operator.

Its amazing how many blogs you get a chance to read and comment on when you can’t sleep! Rob has written some software that can be uploaded to a Linksys WRT54G wireless access point that forces people to go to a html page of your choosing when they first use your access point. This is similar to the way commercial wifi providers work. You would then normally sign up for a limited period of access, but in this case you would probably acknowledge the accesspoint owners “welcome” and info page before continuing to surf. A neat hack – shame it won’t work on my netgear box although I guess it won’t be long before something like this will get hacked to work on other machines.
