In this chapter, we'll look at the most distinctive feature of Neutrino,
Message passing lies at the heart of the operating system's
microkernel architecture, giving the OS its modularity.
One of the principal advantages of Neutrino is that it's scalable. By scalable I mean that it can be tailored to work on tiny embedded boxes with tight memory constraints, right up to large networks of multiprocessor SMP boxes with almost unlimited memory.
