Gnuplot is fine until you want to do something like plot the time
varying electric field around an antenna in 3D with little arrows
showing the Poynting vector. I did start writing a little library to
take the output of NEC (EM modeling code) and generate POVray input
files from it. But I got distracted by other things.

That's the price for a student getting a copy for their own machine.
They have other schemes for students running on university owned
machines, etc. (all carefully designed to avoid rampant illegal
copying, I'm sure)
You do raise an interesting question. Would one student running an
application on N machines need N copies under their academic student
And, most universities, I'm told, require undergrads to have a
computer (even a certain type of computer).. how long before they're
required to have a cluster.
