I think there's two different things we're talking about here, one is hiding things and the other is using obscure ways of doing things. Changing your SSH port is the former. Using NETRJS instead of SSH is the later. Hiding things is just a good security practice in general (just understand hackers have access to port scanners) so that kind of "security through obscurity" isn't a bad idea. Using obscure protocols is something quite different, and really shouldn't be in the same category.
