One of the things I've always liked about Sonar is that it is a simple activation process, that doesn't rely on an external server, always on connection, dongle or any of that jazz. I do computer support for a living so I've seen all of the myriad of problems those license systems can, and do, cause users. I really debated if I was willing to buy Eastwest's Play when they announced it with iLok.
So thanks for not hurting your legit customers in a probably futile attempt to prevent copyright infringement. I really do appreciate it, and it is part of the reason you keep getting my money.
