Can somebody connect to the console too and see what you are doing, and
interfere with it?

The pointer doesn't show up in X terminals, but from the point of view
of applications, they get mouse events etc. from libgpm just as if they
were run on the linux console.

So I believe it's simply access to the hardware console.

And I'm on the contrary sure that all these ways fall into two
categories:

- access to the physical console (/dev/tty[1-9]), in which case you
already have access to it, type things, etc.
- access via network (ssh, telnet), or serial (/dev/ttyS0, etc.) in
which case you do not have access to the physical console.

It's only part of the VT subsystem.
