Nice pointer, did not know about that page :) Another interesting approach for ODE that I did not see mentioned is that of Taylor integrators, e.g.: http://www.maia.ub.es/~angel/taylor/ It should not bee to hard to wrap in Python using Weave and translating symbolic expressions into the text format used by the integrator.
