Ask HN: Would you pay for a cloud/hosted version of an open source project?

Hello fellow HN-ers,

Let me put some context: I'm running a free service, mainly focused to the developers and tech savvy. I want to monetize it, of course, but I already made it open source from day-1, under BSD license, and I don't want people think I'm a dick, also, there are some people already contributed to the project.

I'm thinking of rolling out a paid plan for using cloud version of it, and if people don't feel like they should pay me, they could always host it themselves on their own server.

The paid plan will also contains some exclusive features that will not be available in the open-sourced version.

Do you think this is a reasonable approach, and if you're my user, would you willing to pay for it?
