I had read somewhere that you can run more than one app at the same time on Intel Edison Board. For example, I want to have an arduino program running to take sensor inputs, control motor, etc. and depending on some conditions arduino program will then send data to node.js app to run and send webcam data to dropbox. I think this is possible but don't have to do it. This will be helpful in many cases since arduino has a lot of libraries for sensors and actuatora and node.js is too helpful for tcp, socket, webcam, sending mail, etc.
