Nice idea. But there are still problems with reader macros.  E.g.
input like

(progn #.(print 'foo) <RET>
)

would print FOO twice.  If you want to add this kind of state to the
protocol it might be easier to make the REPL read from a custom stream.
The stream informs Emacs when more input is requested.  The REPL in turn
tells Emacs when to print results and prompts.
