Distributed applications that handle UI event processing via spanning it over a network connection are ill conceived. They get hung up and stiff the user with baffling (and inconsiderate) non-responsiveness when the network flakes. They only behave reasonably when network connectivity remains ideal in all respects.
GWT apps, in contrast, are written in Java source code but their UI behavior executes entirely in a client browser. The only network interactions for GWT apps (other than initial loading) are async RPC calls - being async they don't block the UI thread in any manner so the UI remains responsive at all times.
Same goes for a Flex app that uses HttpService asynchronously or the bi-directional messaging XmlSocket class.
