@Charred - Well, I don’t know how much of today’s Internet uses frame relay really. The article seems to imply that this technology is for retail WAN networks, not for the Internet as a whole.
However, there is always a tradeoff between speed and accuracy with these technologies in my opinion. If you want it done fast, don’t spend too much time checking for errors. If you want one hundred percent accuracy, expect a little delay. That seems to hold true in a lot of areas I would think.
