I think it makes sense.  Traditionally, DISPLAY=:0 means "the X server on
the machine where the client is running".  You can trivally
  export DISPLAY=`hostname`$DISPLAY
and Slurm will be happy, won't it?  IE, you have given it an actual 
network-aware DISPLAY setting.

But isn't the case being discussed where the submit host actually is 
running an X server, and also on the same (trusted/routable) network
as the compute node?

In which case you don't want Slurm doing anything at all.  Just let the 
X client read DISPLAY from the environment propagated by Slurm.
