All of your work products that are created and sold while your corporate membership is valid/active are covered by the special license. However, if your client takes your work product and redevelops it, making substantive changes and starts selling it or charging multiple customers access/usage fees for the new/enhanced product, they’d need to get a membership of their own because they’d be doing development work that leverages GreenSock code outside the scope of the product you created for them.

In terms of liability, your responsibility in that scenario is to communicate the licensing terms to them (tell them what’s out-of-bounds). I certainly don’t expect you to control them. They’re responsible for their own choices. Please just make sure they’re informed and that you abide by the license agreement (which is actually rather permissive).

I would only purchase the single developer license, naturally. What if a client to whom I am delivering code for a project that falls under the constraints of the commercial license sometime in the future goes with a different developer or developers, but continues to use your libraries in the project without their own valid license? Who is responsible for holding the license at that point? The client and the new developers may not be aware that they need to have a license. Would this in anyway be a legal issue for me as the original developer and license holder?

Thanks.

If I were to create a website that:
1) Uses Greensock software to render data (say images).
2) The website is free to browse and display these images.
3) A subscription fee applies on the website to, say, view other premium content (such as videos/music) that doesn’t explicitly use any GreenSock code above what is available freely.

Would I need a license in this case?

I have a question about the license: do I need to buy a corporate Club GreenSock membership if I use TweenLite to make an advertisement for my commercial website which is freely accessible to anyone? Some people will purchase things on the website, so I wasn’t sure if it requires the special license (You mentioned that if multiple end users are charged a fee, I need the license).

So, let me see if I have this right…

If I make a game that uses TweenLite, and sell said game to Company B for a one-time fee, and Company B hosts said game on a site that does not charge end users to play it, I don’t need a license?

BTW, I fully intend to get a Club Greensock membership (corporate or otherwise, as needed) as soon as I’m sure I can make money making Flash content.
