Notice in the later releases of OSX, the transparency got toned WAY down from the early versions. The transparent unfocused titlebars went away. Also, while the menus are still transparent, they're only very slightly transparent to the point that I wonder why they even bother. The key issue is contrast between foreground and background. If you just layer text over text, they compete with each other. Transparency could be made workable by *blurring* out the background, to reduce its contrast. This could be done with pixel shaders, however do any of the open source drivers support them? (Let alone the hardware itself...) You could also fake it by re-rendering to a lower resolution then scaling it back up. Looks like Vista is taking this approach...
