Other than intentional or accidental damage by users, there are others
things to do, like to not permitting pointing the sun during daylight
hours, wind and rain protection and so on.

For mounts, another thing is, in case of a german mount, the meridian
flip protection.

More, we need to block GOTO commands from users when the ccd is doing an
exposure, but this isn't safety related by itself.

Anyway, we implement all those protection on the server side of the
system, cause the client can be modified or rewritten in a different
manner by a skilled coder, so, protections on the client side aren't
secure by definition.
