I've noticed that when making ssh connections my DISPLAY variable gets
set to something like :10 on the remote machine, but when I kick off
an X application, it displays locally on :0.  Is this port forwarding
or something different?  Any X clients kicked off this way will be
encrypted through ssh, yes?
