I just found this while aimlessly Googling around:https://gist.github.com/Benvie/5020656It's a complete implementation of the ArrayBuffer and DataView objects (but not typed arrays, apparently) for non-supporting JS engines, including ES3. It might be interesting to see how this performs in Sphere 1.x; I'd expect it to be pretty slow compared to natively-implemented buffers, but who knows?
