Guile (since 2.0) is now an embeddable VM = and a collection of compilers to that VM. It can run Elisp in the same = way that Emacs can. Thanks - that helps tremendously.

The low-level Elisp that implements the = compiler would also change, but almost all Elisp would be untouched. = There would be some technical advantages, and I can think of one = possible technical downside. (I'll write more about those if anyone's = interested.) I'd be very interested in your views of both the advantages and = disadvantages, for one.
