What's the Right Amount of Copy Protection?

WPIDalamar writes "I'm currently working on a piece of commercial software that will be available through a download and will use a license key to activate it. The software is aimed at helping people schedule projects and will be targeted mostly to corporate users. With the recent Windows Vista black screen of death, it got me thinking about what sort of measures I should go through to prevent unauthorized users from using the software. While I don't wish to burden legitimate users, I do want to prevent most piracy. How much copy protection is appropriate? Is it acceptable for the software to phone home? If so, what data is appropriate to report on? The license key? Software version? What about a unique installation ID? Should I disable license keys for small amounts of piracy, like when there's 3 active installations of the software? What about widespread piracy where we detect dozens or hundreds of uses of the same license key? Would a simple message stating the software may be pirated with instructions on how to purchase a valid license be sufficient?"

The only copy protection you need is something to detect you're inserting a disc/disk into the system, then have a black guy which raps with artificial intelligence to interact with the user.

None.

Wrong, everyone has the right to protect something that they've worked hard on. What if the product you made was your only source of income and no-one bought it but everyone had a copy of it? You'd do whatever you could to protect your livelihood.

Get out of your fucking tree, cut your hair and get a job.

I've done the same sort of thing with my GPL Palm software, Contraction Timer.

Whoa, hey, back up. Contraction Timer?

Husband: Honey, can you just hold it a second longer?
Wife: STOP PLAYING WITH THAT $#!$(@)#$! PALM AND GET YOUR ASS IN THE CAR!
Husband: But I almost have it uploaded!
Wife: You have no chance to survive make your time.
