Sure - any moving vehicle can act as mobile hackerspace. I guess it does not need to find a used greyhound bus to build a hackbus - although it looks nice, as you could see at Defcon: http://www.flickr.com/photos/stits/3789808630/in/photostream/ (so at least in California the "hackbus" plate is already taken)
In our Austrian team we use a modified camping bus. But we don't do the lectures inside, we use it for transport only. And we set up a tent and some tables and benches if we do an outdoor session (it usually does not get too hot outside). Here are some fotos on facebook: http://www.facebook.com/pages/The-Hackbus/119262424775334?v=photos And: Be a hacker, then even a saturn 2001 will do. I mean, "saturn" and "2001" should be enough inspiration. fra ----- Ursprüngliche Mail ----- Von: "William Heath" <wghe...@gmail.com> An: HACKBUS@LISTS.MONOCHROM.AT Gesendet: Donnerstag, 22.
