When you think about it, it's pretty weird that we've had resumable, buffered streaming video modules for server-side stacks for years now, but nothing standardized for sending data in the other direction.

I guess getting things into the server stack can roll out slowly, with very limited and spotty adoption.

Browser support on the other hand...

Suffice to say, that even without the open warfare between rival browser projects, and nightmare-mode security vulnerabilities in common browser plug-ins, it will only make a difference if hundreds of millions of users actually latch onto a new protocol, before it becomes something of a norm.
