As I'm sure you know, OSX does support X11, so your plan will work fine once you get past the audio issues. You might check MacPorts and Fink to see what they've done about audio. Yes, Darwin is Unix, but it's a Mach microkernel wrapped with NetBSD libraries, a very different design from Linux which is a gargantuan kernel that does everything. The main issue in your case is that sound is part of the kernel in Linux, but not in Darwin and that there is no standard sound API for Unix. I know that problem has been solved, because I've seen claims of having GStreamer working on OSX (not working particularly well, mind you, but working).
