[Wine] MacOS X cocoa and carbon for Linux?

[hahomir4ev]

Do you know about such implementation of the Mac OS API for Linux ?
I was thinking would this be hard to be done ? Having in mind that the MacOS and Linux OSes have much more in common than Linux and Windows. The benefits of such projects will be great , as there is great diversity of applications for MacOS ,and if they can be used native in Linux there will be great advantage for all Linux users.
