Transferring ‘ownership’ of a simulacrum

Part of the spell description of Simulacrum states:

At all times the simulacrum remains under your absolute command

Is there a rules legal way for a caster to transfer this ‘absolute command’ to another character? Assume any option from D20 Wotc published material is available in order to achieve this.
