For those who are interested in a VNC server/viewer that scales nicely to a full 640x480 display, showing a combination of "track" and "now & next", you can try out something I developed based on wfaulk's VNC server.

It is available at http://strobos.cee.vt.edu/EmpegVNC

I did it so that I can see my empeg on the display in my navigation system and/or my TV in my living room. I still control the empeg with a remote that sends signals to it via an IR-Extender.
