@Vikash: you're very right, when the lib is local, the lib can't really be shared with other devices... unless you decide to define a master computer that manages the lib locally and have it sync'd to a Nas folder. Even though, if a user of one of the other devices that connected to the NAS synced lib files, add his own music to the collection, it will overwrite the NAS lib file, but the master computer will re-overwrite it on sync.
I wonder what happens when u put your .itl file on a dropbox synced between all the users...it might be a great idea... specially since dropbox (or other sync services keep the many versions of your files).
