I expect you can run it in headless mode (new --headless switch), start a Swank server (the backend of Slime, the backend of the most used CL "language server"), and connect to the Lisp process from home, through a SSH tunnel. And control the browser from the Lisp REPL, or a Lisp script, like we would with any running Common Lisp program.
