It's not so much that I think it's "not safe" to have an SSH port connected, as that I'm very aware of my lack of knowledge in this area. As best I can tell, an SSH port (with all the obvious precautions) open on the net would be absolutely fine. But at the moment as it turns out, I don't think I need it (as mentioned above, the focus of this post was on how paranoid other people felt the need to be, not on technical solutions), and I've found myself reluctant to take that last step.
