As far as I Know, you can call mathematica from Sage, can't you?
considering that Sage already gives you Python, Ipython and a notebook much
like Mathematica's, wouldn't be easier just to use Sage, and call
Mathematica when you need?
look at this blog post:
http://sagemath.blogspot.com/2007/12/sage-mathematica-and-hiking-to-vultee.html
and also this section of the sage reference manual:
http://sagemath.org/doc/ref/module-sage.interfaces.mathematica.html
my 2 cents,
Flavio
