Dan writes "NetBSD's Emmanual Dreyfus says that COMPAT_DARWIN is now able to run Mac OS X's XDarwin (this is, the X Window server for Darwin). The server is fully functional: display, keyboard and mouse work. He says that running Darwin has no interest in itself, but having it working ensures that NetBSD's IOKit (1) emulation is good enough to be used. Darwin is Apple's Mac OS X core. A fully functional Darwin binary compatibility on NetBSD/powerpc & NetBSD/i386 will imply getting MacOS X libraries to run any Mac OS X program, just like NetBSD is now able to run binaries from Linux, FreeBSD, Solaris, and many other OSes."
