I'd be more concerned about the connection just dropping out from some interference, and it not shifting or a shift being delayed, than of someone else shifting for me, which I think is likely a completely unfounded worry.
It looks like its using Blueooth PAN to make the connection. There's no security in it as far as I'm aware and the technology is still new so that may change. The only way to sync a device is by having physical access to it. So yes, my concern would be more about interference.
