Echo JS 0.11.0

No.  Limited support, nonexistent team, it's trying to do far too much in one module to jive with the JavaScript philosophy, and it's got a janky old, awkward jQuery feel in the age of the SPA.  

It's not really a matter of whether or not the thing stands on its own merits - it's cool enough and might've even gained more traction if it had come sooner - it's just far too late to the game with far too little to show for it.
