TapeWorm: Not really. In the private sector various forms of DRM are used to deter copying.
DarrkPhoenix: I'm aware that there have been numerous cases of DRM used in highly specialized private sector software, but I'd still question whether preventing piracy was still a rational reason for the use of such DRM. My understanding is that worries about BSA audits and lawsuits over license violations are far more of a concern than DRM which most competent IT departments could bypass without too much trouble. It's also my impression that the inclusion of DRM is often a dealbreaker for the purchase of specialized software unless a PHB is involved. I will readily admit, however, that my understanding of these things stems mostly from Slashdot discussions of such issues (not exactly an unbiased group), and as you seem to have infinitely more first-hand experience surrounding this specific area than I do, if you come back and say that DRM is actually a meaningful deterrent to the piracy of specialized business software then I'll take your word for it.
I don't think I'm an authority on the subject, I can only draw from personal experience when dealing with the business side of software development.
I can't say definitively that DRM is working as a deterrent towards piracy of specialized software and I can't say definitively that it isn't (I just don't have the numbers to back it up either way and just like the consumer level software stats -
no one really has accurate numbers). But I'll say that they 'think' it's a deterrent, and because you don't see much piracy from the private sector they 'think' it's working. Again I feel that's specious reasoning. For my company, DRM is unnecessary and unwelcome - just another thing to test and just another thing that gets in our way.
I can't say if I've ever heard of the inclusion of DRM being a deal breaker for private software, but I wouldn't be at all surprised if it's happened before.
Audits of licenses and the like are definitely a concern (and a far better deterrent than DRM let me tell you) and the groups doing the auditing don't care whether you call it a license violation, piracy or software usage efficiency, to them it's grounds for a massive lawsuit. This isn't just devastating financially, but it can destroy that company just from bad PR. It's funny, if I call Microsoft and say my neighbour is pirating Windows, they'll probably say "fuck off, we're busy" - well, ok, maybe not, but they won't likely do much about it. However, if I called Microsoft and said, "my company has only 2 licenses for windows and it's installed on 10 machines", you can bet your ass they'll be beating down the door with lawyers. Of course, Windows is commercial grade stuff, but it's used by private and public sectors alike and how Microsoft treats the abuse of its products can vary depending on the context. But notice I didn't mention anything about DRM, that's because it's not a factor, it can often be bypassed easily enough.
Frankly in the private sector fear is the motivator against piracy more so than DRM (I know it is for us - we license EVERYTHING, no matter how small and unenforcable it -might- be). This is especially true if you're a larger company and have a lot to lose. This is why I don't think it's a valid in the argument for or against DRM. The world of private software tends to operate differently on many levels.
Regardless, this is moving outside of the intended topic of discussion for the thread. No one here is dealing with private sector software that installs drivers that forces CD/DVD drives to read outside of their physical parameters... they're dealing with badly designed commercial grade DRM. Although, I'd love to see someone pop up and say: "FUCKING HOSPITAL DATABASE DRM JUST FUCKED MY DVD DRIVE!!!" (and be serious)
A facepalm moment for sure.
