RCI Bed Rack anti theft?

Attention bed rack owners! (RCI or otherwise).
I finally bit the bullet and ordered an RCI bed rack, and then heard how easy they are to steal.

Have any of you guys come up with a way to prevent theft on your bed racks?

I was thinking just plain security hardware (like the torx bits with the little pin in the center - then again, anyone can just buy the bit at home depot).

Perhaps there's a way to rig up a locking wheel lug as part of the mounting hardware.

I suppose I could just take it off and store it when I'm not actually using it. But I'd like to keep it on full time.

Any thoughts?
