Well, we know what Thompson wanted:

"My ideal for the future is to develop a file system remote interface (à la Plan 9) and

then have it implemented across the Internet as the standard rather than HTML.

That would be ultimate cool."

It would.

Betreff: Re: [9fans] Will the future Internet resemble Plan 9 namespaces?

Possibly. I think though that the old adage of "Those who don't know unix
will imitate it, poorly" will apply here.
Really I think that's the internet in a nutshell. Http is like 9p except more
complex and less flexible, as is ftp. Email is a mess and in a similar state.
I think whatever imitation of namespaces gets done for the net will be in a
similar state.
