Rob Howard asks the question Is “Smart Client” a “Dumb Idea”. Obviously I don’t necessarily think so as I pointed out in my post Overlooked Problem With Web Based Applications.
However, as I thought about it more, I realized that part of the excitement over web applications is that they are starting to really deliver on the failed promises that Java made...
Write once, run anywhere.
Although closer to the truth is...
The missing piece in my mind is that there is no built in support for managing local storage of your web based data. As websites get richer and richer, perhaps Smart clients aren’t the only way to solve this problem. All that is necessary is to develop an HTML specification for saving user data to the desktop.
When you reconnect, your browser sends the document to the site which merges your changes, giving you the option to resolve conflicts. It sounds a lot like smart clients, doesn’t it? The obvious difference is that your application would theoretically run on nearly any machine with a modern browser that supports these new standards and would not require the .NET platform nor a Java virtual machine.
In any case, this is my hand waving half-baked view of where we’re headed with web applications.
