I thought about making something like this ten+ years ago, for dvd, but
I guess for USB/etc it is the same principle... 
a read only, write once file system with very strong encryption and code 
for unlock/write/updates (and of course brute protection, etc - i did
make a poc and published it somewhere, am looking for that now, but I
am surprised that such an animal is not yet out there? surely it has to be?
