Well, actually it could be used as an applet, by using the JRE 1.2 for
Other platforms will not work in the general sense. For other platforms we've
it through how we're going to make it work. Maybe by using the servlet
mechanism and sessions. The applet would have to work by sending commands
and receiving replies for these platforms (I don't know if we'll implement
