“PirateBox is a self-contained mobile communication and file sharing device. Simply turn it on to transform any space into a free and open communications and file sharing network.”-David Darts
This little box is like having your own short range torrent server to take anywhere you may go. And you can even make your own PirateBox too for as little of costs as $35. Now there are a few different variances to build whether you want to build a stand-alone or run it on a existing device, you can even put it on your phone. Did I mention it has a integrated chat feature?
