As a private user, the best solution I found was to go through BTSync set on a limited set of document folders. It doesn't need to forward ports or expose the login system. The BTSync server is still a vulnerability, but it's under it's own user and should give less exposure than the other services like the DSFile that check the login/password. Potential damages on a simple breach (i.e. the sharing key leaked or was guessed) should be limited to the shared folders. I hope.
