My guess, this will be another scheme where the network driver on the client has to respond to congestion control/back-off style requests from the AP, staying off the air for a (random?) amount of time. The AP will just be slightly more sophisticated about who it tells to back-off. Even NTP has this feature.

"It's true enough that a properly encoded Ogg file (or MP3, or AAC file) will be indistinguishable from the original at a moderate bitrate." Rubbish. Any lossy format but particularly mp3 sounds GRUESOME to anyone with a trained ear. And untrained ears can certainly tell the difference once it's pointed out, usually on a good system. If you want to know how to get 11:1 compression ratio on a pseudorandom source like sound, it's simple - they throw away most of the information ,particularly spatial information in the upper frequency ranges. You can't "hear" some of those frequencies, but you can certainly perceive when they are absent. I personally cannot stand mp3s and never use them. FLAC all the way.

A definite bias in the comments towards supporting academics. My views, based on firsthand experience, are the opposite. Firstly universities are places where the fruitless, unproductive and unrealistic go to wallow in low-demand jobs. Most academics have little experience of the private sector and are not even aware of this concept of personal productivity (yes even in Economics departments!). However universities ARE a massive and sometimes useful pyramid scheme where you take a bunch of students, incline them towards doing Phds, employ most of them, and hope that a handful of them earn your university some respect, and even that one or two may win a Nobel or and bring actual prestige. This is the real cycle of the university business - promote itself, buy in productive academics, publish more (not better) papers, grow funding, get more students, review rankings and repeat. Good "science" (not an all encompassing term for the areas of research at universities) is as rare as good government. A thorough de-weeding once in a while can only be a good thing, and a handy wake up call for those that remain. Good riddance. No one any good will be losing their jobs - not a one.
