Since students may be interested in viewing multiple streams at once (for example, one stream showing the overall demonstration of the experiment and one showing a magnified view of a particular bacteria culture), then the interface should be able to automatically resize and tile individual streams to display them all at once while best utilizing screen space.

There should be some equivalent of a "pointer" on the video broadcasting-side, for highlighting important information. There might also be a "pointer" for pointing out comments on the receiver's side, though this would probably cause more trouble and distraction in the classroom rather than promote useful feedback to the presenter, thus this probably won't be implemented.

For the sake of cpu usage efficiency on less powerful machines like XOs, annotations will not be encoded as part of the video strema; they will instead be transmitted seperately from the video file, much like external subtitles, in a format using a simple coordinate system (time, x, y, color) and would be overlayed on top of the video via following decoding.
