It took a bit longer than expected, but I've finally gotten ahold of Leopard and am happy to report that Pomoto runs just fine. Of course, if anyone has any problems, please be sure to let us know.
Apart from the horrible default dock and translucency in the menubar, I'm enjoying Leopard quite a bit. Personally, I highly recommend putting your dock on the side (I'm a lefty myself) and using the 'Earth' background. Not only is it beautiful and in-line with the 'Space' theme of Leopard, but the top and left borders are completely black which makes the menubar and dock sane once again without installing any hacks.
