There are many ways to establish desirability for a product, but asking potential users is not the best approach. What people say and what people do (whether they actually do use it/pay for it) are very different things.
One idea: setup a landing page for the product and gather emails from those that are interested in finding out more. You'll get a sense of the number of people interested and a mailing list for marketing / research purposes.
If nobody bites then it wasn't such a great idea and you haven't wasted the time building a product nobody wants.
This is just one simple idea straight from the lean methodology. There are plenty more ways to establish desirability.
