It's pretty close to the Blender story - where a closed source but active community decided to open up the source code in order to grow the community. See "3D software Blender's "community buy out" in 2002" - http://www.blender.org/blenderorg/blender-foundation/history/. I was at the launch event, and they faced many of the same code issues that the LiveCode community now face - a large amount of legacy code written in a way which was difficult to open source. Blender is now the preeminent open source software for 3D modelling around the world - and LiveCode has the potential to be much bigger - as it applies to a more general audience of developers interested in desktop, server side, mobile and tablet apps across multiple platforms - in a language which is literally child's play to learn. Anyone interested in getting more people into coding, and therefore getting a wider understanding of some of the most important technologies that are shaping our future - should give the KickStarer a look. This is more than an educational project, it is about democratising programming - http://www.kickstarter.com/projects/1755283828/open-source-edition-of-livecode
Yes - interestingly buried away in the KickStarter is the description of an "Open Language" feature. This feature is particularly interesting with regard to the ease of creation of domain specific languages. In many ways the object oriented nature of much of the code base is hidden behind a language and conceptual model that allows a more intuitive use of object oriented concepts, and wraps these in a DSL. Opening up the source code will allow us all to create truly natural DSL for a whole range of open source low level projects.
