I've not tried it for such large scale problems (I've only gone to 4 or 5
coupled ode's).

As you say, the underlying code should handle it.

The only question is how long will it take.  Using Numeric arrays in your
function to compute the derivative is definitely recommended, to save

Why don't you give it a try?
