Mobile phone systems should be designed to detect and deny service to
misbehaving devices when it is necessary to preserve the integrity of
the community resource.  If someone wants to hack the phone network,
they'll find a way, replacing the ROMs or whatever - security through
obscurity is unreliable.

That's depressing.  If I end up as a user of a medical computer (which
seems likely at some point), then am I no longer deserving of free
software's freedoms as much as possible?

Verification and authentication are the keys to these problems, not
unmodifiable software, whether through ROMs or tivo-style locks.

Voting black-boxes seem impossible to use safely, so should not be used.

Hope that explains,
