I agree that the effort is large, and the browser platforms are constantly in motion. I was mostly just musing about it. My gut feeling is that getting Java script up to speed on the server side is just as much if not more work. Look at how much work has gone into the tools just for Java for example. Years. Before I get flamed, I will say that I am not bothered at all that some folks are willing to take up the effort to do it anyway. That is how things get done. I am just wondering about it.
