I'd like to propose a change on line 197 of juce_posix_NamedPipe.cpp, this would allow us to create those FIFO files in our chosen locations, this would help with security and flexibility (otherwise we always get FIFOs in /tmp/)
pimpl = new Pimpl (File::isAbsoultePath(pipeName) ? pipeName : "/tmp/" + File::createLegalFileName (pipeName), createPipe);
