Please do not sync over an internet connection or any other wireless connection. One hiccup and your database is trash (maybe on both sides). This is easy to happen considering that you are directly accessing all the data and transferring it to the computer you are using it on, and then updating tons of data to the host computer. This is happening back and forth as you are using this system. A malfunction is very dangerous to your sanity.
If you can, use Logmein or an equivalent. This way, even if you lose a connection, the host computer (the one you are controlling) is just sitting there with no more input until you reconnect. Nothing is destroyed.
