In principle. I guess it depends how amazing your plugin is as to whether
they'd bother. But I was thinking if you have an "add noise" function then
that's going to be pretty easy to find (even by trial and error, skipping
each function call in your process routine one at a time). I've never tried
cracking anything, I only know from feedback that some things are easy to
crack... a function call is definitely easy to patch.
I thought the suggestion of shipping the demo with missing features (not
even linked in) is a good one.

Well, for example, instead of just crippling the plugin you could ask the
user if they want to buy it (with a popup screen at close time, a voice
over, or whatever, there are many ways). Perhaps offer them an incentive to
buy it... tell them what great stuff they're going to get that isn't in the
demo. Positive reinforcement rather than negative (just make the damn noise
go away). A lot of the other suggestions are pretty pursuasive...
I guess I'm just saying that there is a difference between crippling
something so the user needs to buy it to use it, and crippling in a way that
encourages people to buy it...
