Nope: he got off lightly. Research - it is a fundamental skill if you want to be a developer. It isn't as if this is the first time anyone has wanted to do this, is it? :laugh:

I appreciate the sarcastic responses. But my experience up to now has been back end work. Had no need for this information. But, I am glad for people like thatraja and Trollslayer who believe in the success of all and not puerile comments from congenital people.

Solution 1

There are many commercial packages which do this, search for "software licensing software".
You could ask in the Lounge which packages people have used successfully.
