Ahem. Don't we have this already? It's just called "instant messaging" (because name "world wide web" is already occupied for the term describing a system of interlinked documents).
Push-based, aware of devices (and, to the extent possible, of people), based on "messages" rather than "documents". This stuff works great for the latest gossip. The problem is, it doesn't work well for information storage and subsequent (on-demand) retrieval, sans the "recent messages" case. Every instant messaging archival system I've heard of is basically pull- and document- based stuff.
I guess query + subsequent retrieval (pull) can be decoupled into two pushes (push "hey, anyone has this book?" + push "I heard you've asked for this book, here you go") - an interesting idea that some distributed networks already do. But this is still based on concept of documents and content-based addressing...
