Well, the hardware people see a huge difference. To them one is "doing it in hardware" and the other is "doing it in software". I stay on the software side, and see them both as different ways to fake an execution environment. Wine fakes a windows system, qemu can fake a processor (and then either fake system calls for an app or fake hardware for a kernel). Considering that the original goal of QEMU was "to run the Wine project on non-86 architectures" (see http://lists.gnu.org/archive/html/tinycc-devel/2003-03/msg00084.html ) I think making a terminology distinction between Wine and QEMU is splitting hairs. (And trying to draw a line between qemu, bochs, and valgrind is splitting the result of that.) > If I follow your logic, then bochs is also a good canidate for the workshop. If you mean the way Hurd is a candidate for a workshop anywhere Linux is, sure. If it's a purely academic conference where being useful doesn't enter into it. (I followed Bochs and Plex86 5 years ago, but could never actually get them to do anything useful despite repeated attempts. Still haven't, although I see Bochs is back from the dead...) > -- And I'm sorry, but I find your tagline actively wrong: > Infinite complexity begets infinite beauty.
