Hmm not much out there?
What we are doing is applying the moire reduction in Leaf capture ... saving and then running the mos files through adobe ACR... taking a bit if time but it seems to be the only way at present.
When I used to shoot with the Kodak SLR/n moire was a big problem for me. I found the quickest but quite crude way to rid me of the blight from many images, was to select the area roughly in Photoshop then desaturate. I tended to only get it in areas of little or no colour. It felt a bit like spotting a print with Tipex but worked better than it had any right to. It looked better than vomit like effect of moire anyway.
