I have posted Moosh, the Moo Graphical Shell, as a reincarnation of the MAGE client for Magic of Middle Earth. Moosh is a Firefox extension that adds the sh: protocol to Firefox, which permits you to log into M.M.E with a URL, sh://cixar.com. Try it out.
Moosh, at the moment, is merely a graphical shell platform on which we intend to build a local graphical shell with a Moo/Swil idealized syntax. Ryan Paul has also suggested that we might use this platform for a non-interactive telnet client, for logging into MUDs or any telnet service with line-buffering.
