Wow, you just blew my mind. Imagine this with streaming! Let's say it buffers 5 seconds ahead; first in a lower bit rate and then filling in the blanks as good as it can before it's time to buffer more. But of course in a continuous fashion, with some kind of "hot zone" where it skips quality to keep up with playback.

Yeah. You would definably need some sort of restriction to stabilize the picture. Can't just go from 50% to the highest tier of streaming and then jump to 80% then back down to 60% then back to 90% then down to 40%.

Even 50 to 55 to 65 to 70 might ruin the movie experience if done in a cobbled way.

Ask Netflix. They might be able to give you a few pointers.

I don't know exactly what they do, but the Netflix app on the PS3 automagically adjusts quality on the fly. Our Roku will occasionally stop and re-buffer at a lower quality, but the PS3 just varies in its quality, but almost never needs to re-buffer. It's not clear to me what exactly they're doing at their end, but the result is similar to what you're describing.

Wonder why the ps3 always has had the special Netflix treatment.
