I haven't donated yet since I'm not sure if I really need this driver; I can see all the benefits and the fun, but I can see (as proven here already) the potential problems.

It is like being in a hamburger restaurant; I know that if I want that burger I can donate my money to the cashier and get the hamburger. Or I can go home and do it by myself. My friends could come in also and might even donate me something for having such a tasty burger. Or they might not.

The first case is clearly a business with all the responsibilities; ie. I can have my money back if the burger is not what I ordered.

What I mean is that even though being under GPL, when done this way, this is bying a service / driver. To give the customer the freedom to set the price does not change the fact.

But it is admirable that you are wiling to share this freely (eventually) with everyone!
