I fail to see how that relates to my using it as an example of a fast compiler. For that matter, my suggested approach doesn't need to to release source code, just some kind of programming language code. You could minify it, pre-optimise it, or do any number of things that would mean it isn't source code but instead becomes derived code (as I said in my original comment). Distributing textual code is not the same as being open source. I'm really just saying you should distribute something that isn't a platform specific blob with a fixed binary interface. You could, for instance, use LLVM IR code to achieve this, which is little more than a kind of portable assembly. LLVM can apply heavy optimisations to this code on the developer's machine, then take only the last step of code generation on the user's machine.
