Also, in the pynac-based symbolics that Mike Hansen has been polishing up for full inclusion in Sage (to replace the maxima based symbolics), one can just do f.integrate(algorithm="sympy") and sage will compute the integral using sympy.

Cool. Are you going to keep Microsoft Windows in mind wrt SPD? I think the work Dan Shumow (and others) have been doing on the Sage windows port could, in a sense, be seen as a base for a completely open SPD for Windows.
