It would be a really cool function to add a js keyboard shortcut (quake style) to bring up a GateOne terminal emulator over Libre. Then use the html5 terminal emulator to log into devices. You could pass the hostname to GateOne to go ahead and ssh to a node if you are on a node-specific page within Libre.
You could put in a global setting to enable it so those who don’t want to use it can still use their client’s event handlers like normal.
