here's a talk i gave yesterday at RejectJs. the talk gives an overview of the current state of the project, then talks about apps, and then about javascript urls, peer distribution of apps as dns-independent content-addressable content, and goes through 7 levels of inception to arrive at a wildcard hashbang player. It's a bit of a thought experiment, don't try this at home. for instance, the scraper would be very dangerous to use in real life.
but i hope some of the tricks used in here are thought-provoking:
