When, I wonder, will someone be able to build and operate the arm and adder that are the devices one needs to build per http://www.foresight.org/GrandPrize.1.html ?
It is difficult to tell if any progress has been made toward making such devices possible. The only technology I am aware of (I have not done a good job of keeping track of these things the past few years) that I think may be the shortest route is use of wet nanotech and genome engineering to either build tools that then build the devices or that can build the devices directly.
