Indeed, Mach IPC has some nice properties, but the classic Mach IPC APIs are... opaque and hard to get right, and the classical "make it simple to use" tool, MiG, has some problems of its own.

I *do* like the newer abstractions built on top of Mach IPC (xpc, although the data marshaling API is a little tedious, and NSXPC, where the data marshaling is wonderfully).

What I *really* want the BSD family of systems to get, though, is a C blocks runtime and libdispatch.
