That link is interesting. I generally check Ethan's blog, but not today, at least not until I saw your link. I have seen reports of this finding, but hadn't seen a good discussion of it. I have been dubious about it. But I have a lot of respect for Ethan and if he says there may be something to it I will accept that. Of course even he says it may have a problem of some sort. Once again we will just have to wait and see.
