I don't really know what kind of browser they want to make, but if I would make one, I'd add some p2p networking on it, like IPFS or a minimalist databse that runs on a DHT. The end goal would be to have your data hosted and automatically spread on clients, instead of servers. Currently I can't really name a p2p platform which has some usable interface, where you can share content like the web allows it. There is zeronet, but I'm still waiting for a browser all in one package to make it usable.

p2p is the future... (and don't tell me about websockets, they're not true p2p)
