We are Engineering student in electronic and computer science and we work on a project using the A20-olinuxino name "the cowbox".
This project is a hand-held standalone server containing in a little box, broadcasting its own network and containing web applications for coworking. These web applications for example are an etherpad, an ethercalc, a scrum tool and you can also share files via local ftp by wifi.
It was already done on a raspberry but we want to put it on a more performing platform and using the A20 Olinuxino.
