 Seal It or Hack It?

Linux Journal asks if embedded Linux devices should be "sealed" or "hackable"?

"While I agree in principle at the impossibility of obfuscating computer programs, there are certainly points of diminishing returns. If I'm running a piece of code on, for example, a PIC 16F84 processor with built-in MD5 encoding and tamper-resistance protection, this offers a much larger degree of intellectual property protection than an embedded Linux kernel where any attempts to modify the filesystem for this purpose must be explicitly made available under the GPL. "
