While we're off-topic anyway, I do recall hearing a nifty talk 20+ years ago on semi-static translation from x86 to Alpha, both under Windows NT, that DEC implemented. They were worried about the dearth of Windows NT/Alpha software relative to the volumes of Windows NT/x86 software so translation made a lot of sense. I recall the speaker making a point that PowerPoint posed a challenge for them because their tool looked for known compiler code-generation patterns that they could exploit for performance (correctness?), but at the time, PowerPoint was hand-coded in assembly language.
