Since Darwin has a BSD 4.4 environment, would it then be possible to port ABI emulation to it? Does ABI emulation reside as a BSD kernel module? Is it portable to all BSD environments?

Please direct me to any additional info regarding ABI emulation as it sounds to be the best solution.

It seems to me that this would be a very useful feature for those wanting to use Darwin to run native Linux (x86 or PPC) binaries. I'm assuming that a port of X11 would also be required???

Thank you for your post and thanks in advance for any addition help?
