I would love to see something like this included in octave/gnuplot.  I 
know there are good solutions out there for latex (seemingly the best 
being psfrag), however I really prefer pdflatex (because of hyperlinking 
and beamer) and psfrag doesn't work with pdflatex.  Further, it would be 
great to be rid of the direct requirement of manually creating a .tex 
file and compiling with latex, since I often want the same plot on 
screen as ends up in my paper.

Of course there are many hacks that can make this work.  However I'd 
love to see the future of octave (OK, probably gnuplot so that octave 
gets it for free) go in the direction of specifying tex style symbol 
labels.
