I think you can get the closest point on a group of curves, get the point-tangent from there and use that (vector) as a force, combine to taste with turbulence, and perhaps a force pulling towards the curve (vector from point to closest point) for extra control.
adding/removing curves to the group is all you’d need to do to add them to the simulation. hope this helps.

Right now I'm working with Flow Along Curve and a bunch of partially-overlapping curves that go from one end to the other, but since ICE is pretty limited in what you can plug a geometry port into, I'm running into a LOT of duplication that makes adding or removing curves a labor intensive process. Is there another approach to this I should be trying? Thanks, Dave Sisk
