I am the author of the (entirely non-mythical) Andrew System embedded lisp from
CMU (called ELI [Embedded Lisp Interpreter]).  It is written in very portable C
and is available on the X11R3 distribution which can be ftp'd from MIT.  It
implements an "extended subset" of Common Lisp, and is currently in use as a
filtering language for the Andrew Message System.  It is a fairly stable if not
utterly robust package, but when you buy into ELI, you will also be among the
first to know about its upcoming successor, ELSIE (the "Embedded Lisp [Scheme]
Interpreter, 'ELSIE'"), which will be even smaller and faster than ELI and which
will not be an "extended subset" of anything; it will be a proper superset of
the Revised^4 Report on Scheme, complete with a Lisp compatability module and
tons of other wonderful features.  If you are interested in discussing ELI or
ELSIE, or indeed any other part of the Andrew system, please check out
comp.soft-sys.andrew.  Let me know if I can send anyone any more information.
