Sensors fly separately from the consumables, hitching the same ride up. The consumable ones only need their own for final approach which might even be assisted by "painting". A bigger problem would be sensor overload from all the friendlies, you'd probably want those loitering to follow a course determined by a PRNG predictable to everyone who knows that day's key. But that's just very basic crypto put to novel use.
