Personally I've never had the need to enforce licensing to that extent so I don't know. I generally find the apps I write are so specific that I can agree a fixed price for an unlimited number of copies with an upgrade fee when a new feature is required. The app I mentioned earlier would have required a revised price list to be sent to my client's customers at intervals and he wanted to ensure that no one was using an old price list.
