This is essential to me, too. Quote: "There will be no built-in support for synchronizing computers,..." I can accept that, but synchronization with iCal should be "intelligent", so that new entries in iCal (e.g. after a .Mac synchronization with my home computer) are added in OmniFocus and not deleted in iCal. If this isn't possible, I'm sorry to say that the application is not useful to me.
