PowerPoint: Builds

Have you ever tried to follow a PowerPoint presentation via teleconference? Yes, I have heard of LiveMeeting/NetMeeting/Webex, but sometimes, well, those just aren't at hand. Anyway, it works pretty well, until you get into slides with complicated "builds". After three clicks in, synchronizing presenter and audience can get pretty tough. Which suggests a feature (admittedly, very much in the "bells and whistles" category) to show what "build state" the slide being presented is in (e.g., 4/6 would float somewhere near the slide to indicate the 4th build of 6 total).
