I quite like the idea of writing an ODE in SymPy and numerically computing it elsewhere. I could see this going in two ways:
1) Sending simple systems to scipy's odeint - it seems ideal not to reinvent odeint if possible 2) Hook into the code generation module. It would be very cool to generate C/Fortran code for this.
