Is there any way to get this transparently persisted to all of your SSH connections, no matter how deep you tunnel? Something like the way $DISPLAY is transmitted? That would be amazingly useful if so. I tend to do a lot of work bouncing around from one host to another and the ability to quickly "jump back" and reference my starting point would be incredible.
