Does such software exist?
What I'd like to do is keep a set of files updated between two machines using bluetooth so that I may edit them on both computers, and changes get automatically synchronized whenever they are within range of each other. Functionally a little like what Dropbox does via the network. But, without requiring the internet. A lightweight local bi-directional link.
This would be extremely convenient especially if it can also be secure, and it has the potential to be far more secure than something like Dropbox.
