Easysync allows you to synchronize files among different computers. You pick up a directory you want to synchronize and Easysync will perform synchronisation whenever this directory is changed. The server part propagates the sync signal among clients, so that if there is a change on one client, all other clients will perform synchronization. It is based on Unison.
