It was also reported in these publishings, that even the lock bits can become unlocked by brown-out events, if micro wasn't resetted properly!! That would be a desaster for a company needing to hide their code...

Does it mean that using a proper brown out protection in design will eliminate the risk of code theft due to unlocked lock bits. One can take out the micro can get the lock bits opened and steal the code. How about using a micro with in built brown protection such as P89V51RD2 and a reset controller with supervisor such as MAX812.
