You might want to have a look to the FX-87 Interpreter, which
implements the FX-87 programming language designed by the Programming
Systems Research Group at MIT. It is mostly written in Scheme (> 95%)
with some additional support written in CommonLISP (mainly for
packages and hashtables); it runs on top of Jonathan Rees's
Pseudoscheme that macroexpands/compiles R3RS Scheme to CommonLISP. 
We made prototype portings to T and C-Scheme without major problems
but we don't make them publicly available (too tentative).

The FX-87 Interpreter is available by anonymous ftp (pub/fx/impl) on
