 Running "sim sync" to a slow remote filesystem can take a long time due to
 having to check the time stamp and size of all the remote files.  It would
 be good to speed this up.

 One option would be to assume that files are only edited on the local
 machine, which is a common situation.  Each invocation of sim sync to a
 given machine would record the time at which it completed, and subsequent
 syncs would only transfer those files which had changed on the local
 system since then.

 A further optimisation would be to avoid statting all the local files by
 using a filesystem notification API such as fsevents or inotify to
 determine the required information.  An advanced case would also use such
 a system on the remote side, so you wouldn't have to assume that the
 remote files were unchanged.
