Exactly – as I said, if you're looking for anything approaching a 100% "protection", then it's my contention that it will long since crossed that line into obnoxiousness. Your point about trivial DRM working well exemplifies just makes my point –- "does it become painful to deal with your product because of all of the DRM? Do you treat consumers like criminals? Is it significantly less hassle to pirate than it is to buy/rent/view legally (and likely pay for)? If any of those are true, you will tip the balance away from a completely successful business model." If the DRM is minimal and unobtrusive, then it doesn't meet my stipulations, above, and it's probably found some sort of happy-medium. (FWIW, I think most of Apple's DRM approaches in the iTunes store have gotten close, except for the device lock-in)
