Yeah, the Amiga had the 'advantage' of having no memory protection(at all), so you could just pass pointers around =) Maybe the kernel could manage this stuff for your program, or perhaps someone could write a library to hide all the shared memory stuff(ie use SysV IPC calls, but abstract them in a library). > I love my Amiga, still use it.
