Maybe. I'm curious what the effect would be if a single mobile platform provider (iOS, Android) supported a new protocol with a single main free mail provider. Specifically, Gmail and Android could possibly push major change through.

Look at SPDY, it was originally an experiment with Chrome and only a subset of Google services, and is now being deployed to other properties and iterated on rapidly in other browsers, too.
