Love to see Omniture build time dimensions into segmentation capabilities. Example, say I want to create a segment of visitors in Discover (or Sitecatalyst I guess) that came from this particular campaign on this date (or date range) and then observe their behaviors over time. This becomes valuable in looking at upper-funnel marketing campaigns and branding campaigns where you are looking at gaining awareness. By creating the segment you can see if those visitors ever end up doing something you want later in time (such as a purchase or lead).
