Yes, that would be *very* nice!

Using the following code you should be able to connect
to a running csi via telnet:

(use tcp)

; Make sure to start csi with the "-:c" option to force
; display of the prompt.

(define (remote-repl #!optional (port 9999))
  (let ((listener (tcp-listen port)))
    (let-values (((i o) (tcp-accept listener)))
      (current-input-port i)
      (current-output-port o)
      (current-error-port o)
      (when (provided? 'debug)
        (set! ##dbg#command-input-port i)
        (set! ##dbg#command-output-port o) ) ) ) )

When running this with a separate spiffy thread, I had to press
return once on the console where I started csi. From then on
you have a repl in your telnet session.

BTW, has anybody a good idea for a AJAX api? I hacked sajax a little
and got it basically working, but I'm not sure how to integrate this nicely into
spiffy.
