The Yellow Box lives on in a way; Safari for Windows is very much based on a Cocoa runtime for Win32. Safari even ships with some obviously named DLLs which can be used to link basic (non-UI, mostly) demo CoreFoundation-based apps out-of-the-box with the headers from OSX dropped into mingw. I was trying to reverse-engineer the Safari DLLs enough to make GUI apps work a few years ago, but a combination of shifting priorities and a cease-and-desist letter from Apple led me to pursue other things instead.
