One thing I wonder about is - how well does the http server stuff scale? I think using something like this to create a small and manageable RESTful service would be cool to look into. It could help spawn a larger professional market for functional development.
NB. This is more of a Botnet construction kit than a standalone Lisp language. It was part of a distributed computation kit that, ummm, orchestrated disparate systems under the command and control of a single "admin".
(Looks like it has some nice thought put into concurrency, though)
