Glad to see things have calmed down. 
Sorry Jeff, my invite must have gotten lost in snail mail. 
Regarding uxtheme.dll. My concern isn't that you're not using WindowBlinds. It's that uxtheme is not a good foundation. We (all of us) should be very conscious of providing users with a truly seamless experience. Even ignoring the fact it's primitive, it's an engine that isn't under your control, isn't authorized, and explicitly not designed for third-party use. Plus, the fact that to get access to it, you have to disable system file protection.
I would have liked to have seen you guys create an engine or something. A genuine competitor to WindowBlinds. Now obviously, as Stardock CEO, I shouldn't like competition, but I prefer competition over patching uxtheme because I know that it's going to have serious support problems for users and serious user experience problems and users won't discern what the tech was, they'll just remember that when they tried to change from the default look of Windows that they had a bad experience.
You've got the art team, you've got the icon tech, on Vista you have the gadget tech (Windows Sidebar). It's the skinning tech that's the issue. Anything but uxtheme. Anything that doesn't involve patching out system file protection or passing around patched msstyles files. It doesn't have to be WindowBlinds. But it needs to be something that doesn't compromise the user experience or system integrity. I really wish Chroma hadn't died off. At least then you could have gone to them if we pissed you off and licensed their stuff. 
Now, with that said, here are some pictures from up north:
