This is with:

kogs2>/home/utcke% echo $EDITOR 
gnuclient -h kogs31.informatik.uni-hamburg.de -r/r:kogs2:

where I am connecting to an Emacs running on kogs31, and the file is
found on kogs2 using an (old) version of tramp.

Well, the above didn't work (I assume it opened a frame on display
kogs31:0.  So I would need some way to specify the display on which
the emacs should open (maybe $DISPLAY does this already?), and some
way to tunnel that display...

Hmm.  Yes, I suppose you are right...
