Since several persons asked me about it, I'll try to give some status
information at regular interval.

Done:
- Mach-O binaries suport
- mach traps support on i386 and powerpc
- enough support for in native gdb to trace mach-O bins
- reverse engineering mach traps

In progress:
- implement required mach traps

To do:
BSD system call support
signal handling
things we don't suspect yet (multithreading?)
