Will there be a Distributed HTTP?

This isn't distributed, but it might be considered (arguably) vaguely relevant: https://en.wikipedia.org/wiki/Multipath_TCP

MPTCP splits a TCP virtual circuit (connection) up into multiple paths so that the underlying packets can travel via more than one route to their final destination.

It's a very, very new protocol; Linux contains the official reference implementation (which Android gets too), and independent implementations can be found in FreeBSD, F5 Networks' BIG-IP, and Citrix Netscaler.

However, Apple's introduction of MPTCP in iOS 7 is the most interesting: the OS actively uses the technology to talk to various Apple-controlled services. http://perso.uclouvain.be/olivier.bonaventure/blog/html/2013...

As such, it's currently the biggest commercial implementation of MPTCP out there at the moment.
