Hi, Some time ago there was a discussion what example application there could be for quixote. What about a WLAN MAC Regsitry? This could be a good example because it can be used in "real world". What I mean with WLAN MAC registry: You can register your MAC address, so that other people who see your MAC address with their Access-Points can reach you. Last evening I saw a different MAC with my AccessPoint, but I don't know where he lives. With a registry I might find the owner. thomas
