Here is an approach, that looks to me like it works:
The Sword Follows its Assigned Wearer ReTe 60 (R: Touch, T: Ind, D: Sun) Ritual
Transports the item you touch to within a pace of a person or animal, of which you hold an Arcane Connection. If it is not a Terram item, you need to include casting requisites. The transported item will hover near the person or animal, and for the Duration of the spell follow it around at the distance of about a pace. It cannot perform precise or complex maneuvers. At the expiration of the spell, the transported item falls down. The spell does not need any Finesse. It is a ritual only because of its level.
(Base 25 [MoH p.92], R:+1, D: +2, metal: +2, complexity: +2)
It uses an AC to define the person (or animal, because 'we can') which the item follows around, and extends the ReTe guideline for object transport with some hovering and following at its destination.
