So how about this idea then:

Tivo builds a kernel for their box, and release all the sources for how
to build exactly that kernel.

Tivo builds a bios image for their box, and encodes into it the checksum
of the kernel, or at least parts of it that they want to ensure are
present and unmodified.

Everytime the device boots, it checks the kernel image, and it the
checksums match, it loads and runs the kernel, and otherwise it checks
if there is a new bios image with a proper signature, updates itself and
reboots and tries again.

Preventing people from doing things with their own hardware certainly
seems morally wrong, but legally, I don't see any way to prevent it.

I suppose you could say in the license: You may not use this code in any
way if you do what the RIPP/MPAA/etc want you to do.
