Instead of bickering over who copied whom, do something useful and tell us how well this app works, or doesn't. What kind of latency is involved, for instance, using a wired/wireless network connection? How do you switch between computers? Do you need a client version of the app on each computer and, if so, how does it handle different versions for older iterations of OS X? Stuff we actually need to know that's not revealed in the sparse app description.
