the model of plan9 lends itself to a radically different way to interact with pretty much everything. For a plan9-esque web browser, each site - nay, each element of a page - could be virtual files in an fs graph, and as you access pages and content you pull down the local graph into regional cache, and other 9P enabled systems see in your visible overlay that cache set.
You end up with a distributed web without needing low level distributed meshnets replacing old IP tech, because 9P on top does all the work.
Or word processing, the working draft is its own virtual file system with some organization, and collaborative editing is just working on the same 9P Mount, and each hostname can identify the editor.
That might be what someone means by "wheres my web browser?" because plan9 is meant to be an experiment - if the successor to the http / html web comes from anywhere, the best replacement (but probably not the most popular) will come out of radical new ideas like what plan9 regularly tries.
Abaco (the web browser shipped with Plan 9) already does what you're suggesting, using webfs and an HTML parsing library.
It might be possible to replace that parsing library with a version of Webkit or Gecko ported to Plan 9 in order to achieve "modern" web standards support while sticking to 9P and such for the actual network portion of web browsing.
