Cyn.in Desktop (an Adobe AIR app) inherits user’s workflow (access rights) from main cyn.in site and delivers the activity stream to the authorized users. Activities e.g. If someone uploads a file in cyn.in main site, the other authorized users receives a notification from cyn.in desktop and can instantly comment (Tweet) on the content.
