For a more complete explanation of what I mean, check out the old BSD license with the attribution clause. If I released a score to a piece of music under the GPL, then anyone could perform it without giving credit in the program, advertising, etc. An attribution clause, says that whenever the piece of work in question is mentioned, or anything that uses it, attribution must be giving in ads, published materials, etc. This is very different than just leaving the copyright intact with the name on it.
In other words you want CREDIT. ... Like "Nigel Rathbone's Tales of Trailers" or "Marimba Freidkiens Kitchen Sexuality".

Like I'd be much more likely to simply use your idea and write my own code. {Like most everyone else would.} If I were to attribute someone that heavily it would be out of respect... not because of some clause in a contract...
I've always seen that sort of thing as a sort of way of sucking off of the authors reputation in order to advertise a product, anyway. Why don't you wait until you have one and then re-negotiate your contract?
