I'm only familiar with the QNX microkernel from working in safety-critical systems. I'm really excited for the possibility of an open source microkernel getting some mainstream attention, since the benefits (modularity, reliability, maintainability, security, etc.) of a microkernel are just too real to ignore now.<p>Can someone explain how Minix compares to Hurd? In terms of how far ahead both projects are, the differences in their architecture and visions?
