Because of the increasingly availability of computers and clustering capabilities, the U.S. has decided that it can't keep up their policies with the changing technology. The export limitations are going from a four tier system to a three tier, with tier 1 and 2 merging, tier 3 changing, but tier 4 will stay the same." While the new rules still base their country-by-country distinctions on the basis of how many millions of theoretical operations per second (MTOPS) a computer can do, they do seem slightly saner. wiredog points out this story at The Washington Post as well.
