Yoric is working on a "proper" implementation and I'll be assisting in the design work, and if needs be some implementation. I think the next milestone here is a working demo in Firefox with Facebook page load. At a personal level, I feel pretty confident that BinaryJS will help your case. The theory behind the gains was pretty solid before we designed the prototype. The prototype, for me, basically proved the theory. My personal hope is that by the time we're done squeezing all we can out of this - which includes zero-costing lazy function parsing, and on-line bytecode generation, we can cut the "prepare for execution" time by 80%.
