"Trivial" is overstating it, I think. I've seen dongle-based license
code designed such that if you tried modifying the code to skip the
dongle check, the program's pointer arithmetic would go screwy and it
would crash in horrible ways. It was a damn clever design, which I
can't say much about here except that it depended on a fairly detailed
understanding of the innards of several parts of a large and complex
program, and so making the appropriate fix would be a sizeable job for
a very skilled and patient hacker; for example, it did not depend on
branches that were only taken when the dongle was absent.
Of course, it could be cracked, but it wouldn't have been trivial.
