Hello Ben, happy to see you here :o)
Could you explain in greater details how it works? What do you mean by
patching exception vectors? I assume that you must check on exception if
it was caused by a Linux app or a MacOS app (how do you recognize it?). If
it's MacOS, then you have a special exception handler?

And about the kernel module: its job is to handle all the kernel side 
translation between MacOS and Linux. Do you think it would be possible to
make the sources cross-platform (Linux/NetBSD), or do you think it would be
easier to reimplment it from scratch?

Last question: is there any userland program for MOL?
