Well, that depends on where you put the “or” and where you put the “more than one time” and where you put the comma. 😉
If you make it…
“A niche application is an application that is licensed or sold to more than one customer, either for a price of more than US$800 or for a subscription price of more than US$400 per year.”
Then it is generally better and very clear.
If you make it:
“A niche application is an application that is licensed or sold, to more than one customer for a price of more than US$800 or for a price of more than US$400 per year.”
Then it is bad, because the “to more than one customer” only belongs to the 800$. Unless you want that of course.
In any case, I think 800$ and 400$ are much too low values. I do not understand why you want to do this.
What is your idea behind it?
Do you not want to enable software developers to actually earn money with their projects? What you are doing is to stop developers from programming with your SDK, especially indie developers.
If I was selling hardware, I would make sure that everyone and his grandmother wants to develop software for my hardware to boost it. Hell, if someone can sell his software for 2000$ a piece I would congratulate him and give him a price.
Eye-X is pretty much an unknown product with no decent software developed for it, let alone any good games.
Shouldn’t you like…. give people money to develop good games? Instead of putting license restrictions on them? How about…. no license restrictions, but instead a software development contest with prices?
I don’t know… it is not my company, but I definitely would do the opposite of what you are doing.
