Audio plugin development - Windows and OSX - AAX, VST, AU

Looking to work with someone who is proficient in C++ and audio plugin development. The plugin will need to be developed in a framework that can create VST, AU, RTAS and AAX plugins in both 32bit and 64bit formats for Windows and OSX platforms. The ideal frame work will be JUCE, but if you have a framework you believe that can handle all of this then please let me know. A non-disclosure agreement is required for this project and the particulars as this is a unique concept for audio production workflows. You will need to be proficient in copy protection coding and be able to advise on a suitable platform for both online and offline activation or a reliable serial key based system that can operate remotely on a website.
