Take a look at sympy/solvers/ode.py to see what's already implemented. Search the issue tracker for some ideas on how it can be improved. Also, we now have a ton of special functions in SymPy that are defined by ODEs, and it would be nice to implement solvers for them. There was a paper mentioned on some other thread on this list about this too. You can also look at more general algorithms for solving ODEs like ones involving Lie groups (see the ideas page).
