Is there a market for paid Django apps?

Here’s a thought that’s been rummaging around in my brain for some time now: is there a market for commercial, closed-source Django apps? Suppose someone released a high-quality, well-documented, well-supported Django app… under a commercial license. Assume of course that this app does something you actually need, and that the commercial license isn’t odious. Would you pay for a Django app? I think I would. I have no qualms about paying for good software: in the last month I bought some backup software (Arq), started using a commercial ticket tracker (Pivotal) and time tracker (Freckle).
