Does anyone know whether or not NeXT is planning on adding SYSV interface extensions (i.e. message queues, shared memory, semaphores) to MACH? I realize that there are similar mechanisms in MACH. However, it means porting our SYSV IPC applications will be more difficult. Any information would be greatly appreciated.

(I don't know what NeXT's plans are in this regard) It shouldn't be that hard to develop a compatibility library for those (at least you're not asking for STREAMS--whew!). The trick is to make sure things get cleaned up properly if a process dies unexpectedly... (also reentrancy for multithreaded applications) "Doing it right" probably means something you can feed to kern_loader, but I'd try a user-mode approach first. -=EPS=-
