Good luck, let me know if you find something.

Also be vigilant, so if your competition comes out with something almost the same and you can prove beyond doubt they swiped the code without permission, you can take legal action. Put that in your source code, and if you flex your muscles in the language you will scare away many people, and think about putting something easily distinguishable in your code, not just variables names because those are the easiest to change. Copyright does exist on code that you write, because its an expression of an idea.

My only idea is to somehow store most of the code behind a PHP security wall, and somehow (this is the part I don't know how to do) you have to verify that the document is being loaded from your server before PHP will send the data.

Also, perhaps its worth searching for some experts in Flash if you have significant business interests, better to spend a few bucks up front to secure yourself then to fight off someone later.
