If you have a system on your LAN you can throw a simple webserver on (or get more complicated if you want), you could have the roku check a URL every few seconds to see if a command is present (and post an acknowledgement if it finds one), and act accordingly. It's not exactly as easy as just using telnet, but if you made the syntax similar to wait(), and if it returned an object that acted somewhat like an event, it would be good for prototyping. many different cases.
