I saw your post before you deleted it. I didn't get a chance to respond before. I just wanted to say that you probably know a lot more about VM's than I do, and I'll concede that. I don't really know for sure whether switching to a bytecode vm would be great or not for the browser. I know that doing /any/ change to "the web" is a huge uphill battle, and so the ecmascript committee has to make a lot of comprimises for pragmatism. In any case, worse is better, and in the real world we can't have the perfect computer system. Haven't you seen tron legacy?
