We were planning to include DropTun.es in this blog and ebook as it looks like an excellent idea – stream the music from your Dropbox from anywhere. However, as quickly becomes apparent, both the web app and the iPhone app do not work. It correctly displays your files and music and allows you to press play next to all your mp3s. Unfortunately, that’s as far as it goes as the app simply won’t play anything. This addon is best avoided.
