What would really be nice is somehting I can just plug the video out cable from the monitor port on the computer into and it doees the work, like frame brabber / distribution. Perhaps VNC (already mentioned, I know, but it's good) or xtv ? $ apt-cache show xtv | tail -4 Description: xtv grabs the screen of a remote display. Grabs the remote display in a continuously updating fashion, making a TV out of the remote display. Don't know about bandwidth requirements though. But I guess that the need for bandwidth would be decreased by running fewer colours. And if you're blind, you shouldn't need many colurs (no offence intended) ;-) Hope this helps -- *DISCLAIMER* I do not know exactly what I'm talking about.
