That's actually one of the things we're working on. We're hoping to have a fighterjet-like heads up display showing altitude, roll, pitch, etc. that will be overlayed on the stream.
You may consider showing the rocket in relation to the Earth. I tuned in at T+7 and just saw an engine burning, now at T+10 the engine cut off and the thing is in orbit. I have no idea where the rocket is at this point. Would a live Google Earth feed be a possibility?
I think even a 2d map with a dot for the object would be serviceable and neat in cases like this. Maybe draw the flight path in a swath that changes color over altitude.
In example, think how meteorologists on TV use color on a map to show the how much rain has fallen.
dark green -> green -> dark yellow -> yellow -> orange -> red -> blinking purple
Just use a gradient with colors that won't interfere with whatever map you're using. Maybe just "yellow -> orange -> red" as it progresses to its target. Then once it hits it, switch to white, and continue to chart the movement as long as you broadcast.
