So all right, I'm back to my original understanding that there is a fixed mechanical ratio between the front and rear for VTD-4WD. But then what I don't understand is the functioning of the actual clutch mechanism. If the ratio front:rear is mechanical, then where does a clutch fit into that system, and how does it allow for more torque to be transferred to the front differential?

Nomake,
Put simply, the clutch limits the slip of the differential in a controlled manner, rather than in an uncontrolled manner, as with the usual form of limited slip differential.
P.S. A normal unrestrained differential will distribute torque in a variable fashion left/right, depending on load. The transfer system also does so front/rear, and the uncontrolled the transfer ratio, is governed by the inbuilt uneven differential ratio.
