Put some simple tracking in your software. Ping once a day when its running.
If individuals run it, eh who cares. There's a not insignificant amount of people who want to see if the real version would actually work. And see if it'll run on WINE or whatever. Pissing off individuals is how you get to be known as bad.
And then there's companies who run it pirated. Those are juicy targets. You dont even need to be mean. "We saw that your company appreciates the trial of our software on X machines for Y days, and would like to engage in licensing for your department/company."
