Yes, I've heard several similar stories of PC protection schemes that used 
all sorts of 'stealth' techniques to prevent hackers using SoftICE and other 
debuggers on their code.

Of course, at the end of the day, it's simply *impossible* to prevent a 
hacker from ultimately cracking your software.

I'm sure half the schemes on the Apple can be defeated by changing a single 
byte on the disk - albeit after several hours of disassembling/tracing. And 
you can be pretty sure there's no 'stealth' behaviour going on to content 
with...
