Wow – is this for real? Looks like this chap is using symbols and a printer to generate a sheet of paper with a large amount of information embedded onto it. It will be interesting to see if this catches on. As a read-only format I guess it needs to run the gauntlet just like all the other formats do. I think that the cost of read-only media hasn’t been an issue for some time, but the cost and availability of drives seems to be more of an issue.
