That was also my impression. There are at least two groups doing interesting things on this subject - Andy Fitch/Irene Margiolaki at ESRF and Robert von Dreele at APS. I've contacted the first group after meeting Andy Fitch in a XRD symposium some years ago (2005, I think) and they were very kind to provide many hints on sample preparation, which seems to be the hardest thing to do in those cases. We are tempted to think "oh, so do I simply need to harvest a whole lot of small crystals in a loop and everything will be fine?", but it is a bit trickier than that. I am pretty sure they will be able to provide some hints to Anna's case, which seems very similar to a powder diffraction experiment. Lucas Bleicher
