It varies, but in comparison try going to a branded publisher (Focus, FastTrak, any games company you can think of, etc) and try to get above 20% and see how quickly they laugh you out of the door.

Would you have to pay us to sell your 'leet' program? Hell no! All of our 3rd party titles retail under non-exclusive deals (i.e. we sell them and the authors can sell on their web sites too, but only for the same price). Some authors decide not to bother selling anywhere else because we bring in enough business for them, but that is their choice. If you've got a killer app, over time we can make you quite a lot of money - simple as that.
Cheers,
Rich
