+        <para>When will Wine integrate an x86 CPU emulator so we can
+          run Windows applications on non-x86 machines?</para>
+      </question>
+      <answer>
+        <para>
+          The short answer is 'probably never'. Remember, Wine Is Not a
+          (CPU) Emulator. The long answer is that we probably don't want or
+          need to integrate one in the traditional sense.
+        </para>

+          Integrating a CPU emulator in Wine would be extremely hard,
+          due to the large number of Windows APIs and the complex
+          datatypes they exchange. It is not uncommon for a Windows API to
+          take three or more pointers to structures composed of many fields,
+          including pointers to other complex structures. For each of these
+          we would need a conversion routine to deal with the byte order and
+          alignment issues. Furthermore, Windows also contains many callback
+          mechanisms that constitute as many extra places where we would have
+          to handle these conversion issues. Wine already has to deal with
+          16 vs. 32 bit APIs and Ansi vs. Unicode APIs which both
+          introduce significant complexity. Adding support for a CPU emulator
+          inside Wine would introduce at least double that complexity and
+          only serve to slow down the development of Wine.
+        </para>
+        <para>
+          Fortunately another solution exists to run Windows applications
+          on non-x86 platforms: run both Wine and the application inside the
+          CPU emulator. As long as the emulator provides a standard Unix
+          environment, Wine should only need minimal modifications. What
+          performance you loose due to Wine running inside the emulator
+          rather than natively, you gain in complexity inside of Wine.
+          Furthermore, if the emulator is fast enough to run Windows
+          applications, Photoshop for instance, then it should be fast enough
+          to run that same Windows application plus Wine.
