One way to have the REPL respect reader macro characters is by making evaluation on swank return the index of the first character not read, with the client using this as the starting position for the next read.

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.
