I wonder how much would be required to emulate just the Windows system calls (used by normal applications)? I.e. the same way qemu-user emulates the Linux and BSD system calls used by normal apps. WINE does this, of course, but WINE is much bigger than that - it replaces all the Windows userspace libraries. That's much bigger than just kernel behaviour. I wonder how big the part needed just for Windows system calls would be. -- Jamie
