You have to understand that giving to someone physical access to the machine, You are in fact giving him all. All the software solutions to protect the contents could be just simply disassembled. So You can only make it more difficult i.e. by rewriting filesystem so it wont be understandable by other machines, changing boot code or doing something simmilar. But this solution has two sides: It will be much more difficult to support such device. If You want to protect Your code, You can use some kind of hardware keys to decrypt executables "on the fly". Of course this is still not the perfect solution, because someone, can sniff decoded code and use it later. If You want be sure that no one will take out You code, You should implement some kind of autodestruction ( H2SO4, TNT, C4, small nuclear bomb etc...) which will destroy HDD (or all device), when someone will try to open the box. And please think about Open Source - this is also the way to make money. And You don't need to wory about the code securiy.
