As a software and services company we have been using Juce for our tools for 7 years and so far it has been a great experience.
You didn’t give details on the projucer plan, but I hope you don’t expand your target too much, and continue providing excellent tools for excellent developers :
considering how perfectionist and care taking you are, If you provide a tool for newbie programmers, I’m a bit scarred that you will spend most of your time doing babysitting and cleaning the forums after them.
as others said, I think most of your professional user base is ready to pay more. Paying a part of the license price every year is a guarantee that support will continue (also a little life insurance on you ; ) ) plus it is perfectly understandable as your product evolves continuously and considering the incredibly fast bug fixing support you give. I think a lot of companies are ready to share this as an industry effort to make our life better as Juce gets better.
Juce still needs to be better known to non audio C++ developers who are concerned with performance and efficiency.
I found back the link that made me discover Juce the 1st time from April 2005 (btw you should correct the dead link )
You recently did an incredible work with the OpenGL accelerated graphic context, and I think no one knows it in the OpenGL world !
I’m sure a lot of programmers out there would pay a lot to have such a powerful library to create UI over the existing OpenGL context their game/simulation/imaging/broadcast software…
Desktop software development is changing radically, and a lot of people now understand that user interface design is crucial (thank you Steve), but look at how many uncertain platform and API choices have to be made for someone who only wants to create a new, intuitive and responsive software user interface.
Audio people have been the first to have nice UIs, but this is spreading to other fields now and Juce should be known as the best tool for this.
You probably know all of this already, let’s hope it is part of your plan
