The example I attached using "--batch" *does* startup a new Emacs instance on every execution. You should be able to replace the "emacs" command with "emacsclient" (or some windows equivalent) command to connect to a running server, rather than having to create a new connection on every evaluation. By connecting to a persistent Emacs instance much of the .el script I attached could be removed assuming Babel has already been configured in the running Emacs server.
