SaysMe TV is a Flash app that lets you post commercials on various cable channels in certain local markets (not Hawaii, tho).

From just the UI perspective, it has a wizard for 5 steps with an interesting alternative to tabs or a bread-crumby road map: horizontal bars that list top to bottom, with the relevant page below the selected bar (like a window). The progression this suggests is more natural than tabs, while still providing random access and a clear sense of location and direction.
