Have you seen our EXE wrapper alpha as well? It's based on Awesomium, which is basically the Google Chrome browser engine in a standalone EXE. The feedback has been very promising, and it's not even as fast as it could be right now. I'm hoping we can tweak Awesomium to skip the driver blacklists, then we can forget about all the driver updating: you'd have a standalone EXE that runs a WebGL-powered game at near-native performance, using the same HTML5 code, saving our 2-man team from having to take on the 6+ month job of writing a new exporter. It should also be portable to Mac and Linux desktop. Hopefully that will solve some of the platform headaches.
