Looks really interesting - using C++ for the main "business logic" and linking into Java or Objective-C for UI stuff, thereby keeping the main codebase cross-platform and keeping a thin UI layer for the different platforms.

I guess this is good for projects where native UI is important. They seem to link into their own "record" data structure, translating equivalent types across languages.&nbsp;

Really interesting part for me is that you can seamlessly call Java / Objective-C from C++ as well the other way around (I've been having a tough time integrating an Objective-C library into my C++ code...)

I wonder if any of this could feed into JUCE somehow, to allow easier integration of external platform-specific libraries or to make calls to the native UI, translating JUCE types e.g. String and Array into their Java&nbsp;or&nbsp;Objective-C equivalents.
