With the chute, the sail is held in place by tension with and between the
cables.  If you add tugs.  The little ships can move out to push or pull on
spots of the sail that start to flap or wrinkle.  Also could twist the sail
for steering.

For my fuel/sail idea this is especially interesting, since the ship would
weigh less then 0.25% of the total weight.  Being that light, it couldn't
exercise enough damping to stablize a sail thousands of miles across.
