Macrovision is brining-out an Activation Service with their new version of InstallShield. This is very significant because it will eliminate the ability for people to give false serial numbers to the installer, they are using to install their new software with.
This could eliminate piracy completely. I hope that this brings down software prices, but I suspect that it will largely just increased profits.
They have a nice Flash Demo, but with a psychotic woman talking about it, if you want to know more.
