This is what I was thinking, but I personally thought it worth asking
WRI exactly where we stood if using their protocol.

At the end of the day, anything you do to circumvent using their
shared library, WRI could put a stop to without changing any code -
just their license conditions. When Mathematica 10 comes out, one of
the conditions of that license is that you can't control Mathematica
from external programs without the use of the Mathlink library. At
which point, although the code would work, it would be against the
license to use it.

Hence my feeling it is better to ask WRI, and work with them rather
than against them.

'jmath' has existed for years as a nice GPL'ed front end for
Mathematica, and as far as I'm aware, WRI have never tried to stop it.
So I don't think they would care if Sage implement something similar.
But I personally would rather ask. You see a draft of a mesage I
intended sending, but also the negative comments about it, so I never
bothered.
