Here is a link to a page, where development is going on to make Mac OS X programs run on NetBSD/powerpc and maybe on NetBSD/i386. http://hcpnet.free.fr/applebsd.html Could this mean, if it works, new PPC computers will come out and run Mac OS X apps? And apple can't really stop them.
Not So As discussed on /. a couple of days ago this effort will allow the system to "pretend" to be the Darwin layer of OSX. They plan to use the existing Apple libraries (for Quartz, Cocoa, Carbon and the like) to allow actual Apps to run. Unless you have a valid license for OSX having these libraries on your system is illegal. The license for OSX restricts it to being used on Apple hardware.
