I did not criticize your app. I offered that your blanket statement that "The browser is an extremely poor medium to deliver applications" does not comport with my experience. And it looks like I nailed it, too. It is the nature of your application. Had you said "the browser does not offer a real time API which I need for my application", there would have been nothing to say. This is obviously true. Even native desktop apps provide an inadequate environment for "hard RT". So I suspect that is also not a true requirement, either.
