This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I developed one business application for which I'm thinking to use user level license scheme, i.e Lets say if someone purchase my software as "5 User License" that means the s/w should not get installed on more than 5 machines.

Does Java got some API for this?
