A modified Tivo box would not be able to preform it's original task of being a PVR at that point, at least with the content provider's signal. Seems pretty pointless to me. Seems like almost the same thing as not allowing an unsigned Linux kernel to boot on the system. Though it would still be possible to get the Tivo box to play tetris or something like that.
