Very nice collection. A tech at the datacenter that hosts one my servers showed me trick #3 and I remember being thrilled sitting there watching him do stuff on my server and sharing the keyboard to type messages back and forth in vi. My company uses trick #5 as a primary feature for accessing the remote Linux machines that our product is built upon. We have it set up so that every single machine automatically creates a reverse SSH tunnel to the server on boot, so that the tunnel is always accessible in case we need it. Very cool stuff.
