"When you look at a home replacement like LauncherPro, which is primarily developed by one man, it's hard to see how HTC or Motorola couldn't make their skins work as apps. LauncherPro offers home screen previews like Sense, more home screens, and even an enhanced animated widget framework. The only skin element a Market-based HTC Sense home replacement might lose is changing the color of the task bar, which requires root access in stock Android. Although, this could change in the future." - LANjackal from Bookmarklet
