I have used NDSolve to solve DAE's (Differential-Algebraic Equations)
of index 1, but solving DAE's is an ugly speciality all its own and
require a lot more work than ODE's. I suggest reading Brenan, K.E., et
al, "Numerical Solution of Initial-Value Problems in Differential-
Algebraic Equations," #14 Classics in Applied Mathematics, 1996, SIAM.
