This is really amazing and a remarkable technical achievement. Awesome work!

We would really appreciate hearing your feedback on the typed array
proposal sooner rather than later if your larger performance writeup
will take some time. We're in the process of refactoring the WebGL
specification to reference the typed array spec, and would like to
start soliciting feedback on typed arrays in other working groups.
Your work on quake2-gwt will provide an immensely compelling argument
for providing fast and low-level access to binary data in JavaScript.
