Another user Racoon wrote it better than I could: "One of the very few disadvantages of bt sync is that both computers should be on and online while syncing. Well for most people, your phone is always on and always online, so why not use it for central server/cloud? Seems like 64gb micro sd is the most, most modern phone support (if there are phones supporting more please do say) and in case that's enough for you, i don't see why not install bt sync on your phone as well and use it for "server". It's just an idea i just got, so would like to discuss it and see if you guys see any major disadvantages to it? My first thought is how this would affect the battery life? " Would this be possible in future updates? or would implementing it bring down the wrath Apple and get the app banned form the app store.
