piping through tar is my "power move" when I want to steer a new recruit. I just do it casually in front of them... depending on whether they are awed or horrified by that, they'll get more hacky or more formal work.
(...And my axe!)
I usually use ssh (e.g. ssh -L 3333:localhost:3333) and avoid gpg, though I may use lzop depending on link and CPU speed.
