Carry your Internet with you, the WiFi Bedouin is a small backpack that contains an adapted 802.11b access point, RF amplifier, custom power supply and a PowerBook G4 running custom software, MovableType Blog software, a custom chat application, Apache 2.0, the Tomcat Java Servlet Container, and the WiJacker, which translates URLs that have been arbitrarily named for local services. On the front end is mounted the iPAQ 2200, which is a PocketPC PDA. It serves as a VDU for the custom GPS mapping application useful for node WiFi activity.
Now that’s quite a backpack indeed. If you’re looking for something a bit more traditional but with a geeky slant, try the H3 Series Campack from O’Neill.
