It's been done, not just for Scheme, but for many other languages, too
(see <http://grunge.cs.tu-berlin.de/~tolk/vmlanguages.html>). I cannot
vouch for the quality or usability of the various code generators
produced by all these projects, but the sheer number suggests it's
pretty feasible for a wide variety of languages.


There's an obvious motivation to do this: The extensive work that goes
into improving the performance of the JVM and its portability gives a
considerable advantage to the compiler writer.


Google for "Scheme JVM" and you'll get plenty of hits, including the
page I referenced above.
