It works fine from within Vim mostly as is; I had to add the swank
package for some of the code in scraps.lisp to work:

(defpackage #:swank
  (:export #:connection-info
           #:listener-eval))

The response to swank:connection-info (which you have in scraps)

  (swank-protocol:encode-message '(:emacs-rex (swank:connection-info) nil t 1) *stream*)
  => "(:return (:ok (:pid 5976 :style nil :lisp-implementation (:type
  ...

doesn't parse correctly in sync-dispatch-return, which expects
something more like this:

  (:return (:ok (:present ((\"4\" . 1)))) 1)

Other than that, so far so good!  Great work!
