It looks like 3b's slime-proxy project is the most relevant.
js-comint-el seems better for a js runtime operating outside of a host
lisp.

I would love to see a Parenscript mode that interacts gracefully with SLIME.

For me it would be ideal to have a SLIME-derived mode for editing
.paren files, and a SLIME-derived Parenscript REPL that interacted
with the host lisp. The REPL may evaluate Parenscript forms in a
CL-SPIDERMONKEY environment, or it may push compiled code into a web
client via the WebSocket API[1] or some other means--it's really up
the host lisp.

I'm not particularly familiar with emacs lisp or SLIME, but I think
extending SLIME would be the best means of enhancing Parenscript
editing. Slime Proxy seems like the perfect approach (
