Can anyone recommend any software that can be used to combat software piracy?

Create it to be hard to use without proper documentation, online services, hotline, training courses etc. See the biggest ad seller on the NET, growing up exactly on this principle, and compare it with keys-licenses-online_checking approach of old times players...
