My 2 cents: I was thinking, that protection should make, that software run
on device/connected to it PC can't make it brick. Nothing about DRM. In
worst case device should start with default parameters and without
additional apps. But definitely shouldn't be dead. Second chip isn't good
idea. IMHO, the best is separating memory to two phisical chips and have
main software in first (with protection) and additional software/"HDD"
inside second (or protection should block writing to chip below specified
address).
