When it comes to getting Raspberry Pis into schools, I believe that the biggest hurdle is what monitors (displays/screens) the school has available. Perhaps something like this could be used? It's a circuit board that outputs VGA, but I'm not sure of the input.

Or perhaps we could get away with a composite video to VGA socket?
There are cheaper and easier ways to do this using resistor ladders, for example here's how the Beagle guys get VGA from their DVD-D (easily available from RPi's HDMI output):

PS - the input on your link is simple RS232. The VGA output is text only, with the text being sent through an RS232 link. It's not a generic -> VGA converter, it's just a way of programatically putting some text on a VGA monitor at a fixed resolution.
