ok. Play 2 minutes of ads at the start and save a stream. Play another 2 minutes of ads every 16 minutes, then the maximum number of streams is 4. The ads can be received in a single stream or be received after the shorter streams have completed.

Hey, there's a better way. Split the movie into segments: Segment 1: Minute 1. Segment 2: Minute 2. Segment 3: Minutes 3,4. Segment 4: Minutes 5-8. Segment 5: Minutes 9-16. etc. Then send each segment in a loop. Each receiver receives every loop simultaneously. Each segment may start receiving part way through, but then it starts again. By the time a segment needs to play, it is completely received. A 128 minute movie needs 8 streams. While waiting for the first minute, you can play ads :) The shorter segments don't need to be sent for long: Receivers can stop receiving the short segments once they have received one loop of it. When no receiver is receiving a loop, you can stop sending it.
Cute :). Well 8*bitrates, but nice optimisation to make stream count finite. Of course at cost of quality, as receiver needs up-speed of 8x at start. Interesting side-effect, quality increases as movie progresses :) -- ++ytti
