I just read cond-mat/0612590 and got a little despaired, I have been working on almost the same idea for the past month...
I got the idea when I proposed how to do this measurement of fidelity experimentally on quant-ph/0609202, and actually I included some preliminary data in the last figure of that paper (on the dynamics, but I had the same data from the static point of view).
I hope I can still do something with this.
