As I've said I work a bit with Google's Webkit which does Java -> JS. The
cool thing, and one of the reasons we've chosen it over other solutions, is
debugging: using some serious behind the scenes magic, you can actually
debug the stuff on the Java side while it is executed in the browser. (It
involves a special version of Firefox. I'm not sure if they have a modified
JS engine or if they simulate the JS engine's context and are executing the
Java variant of the toolkit code.)

In the case of gwt, it's not "several dozen MB", but it is a substantial JS
library, yes. Since we're developping some enterprisy application that will
mostly be used in the LAN, and mostly by a few people who use it frequently,
so browser caching is very effective for us.)
[is not tg]
Much of tg could actually be used: just push the whole tg app to the client,
using the embedded webserver as the main loop of the app. (No, I'm not
seriously proposing tg should invest any effort in such things. Just
thinking aloud what the current trend to make web stuff available online
might mean.)
[As it happens, I have been thinking -- exactly as nebulously as the above
whacky idea -- in the opposite direction myself: creating tg standalone apps
by using tg controllers and replacing genshi by python-kde bindings ... so
the same business logic could nicely be used for a full application for
power users and a web application for web access. Why? Because I think
that full GUI apps are still better to use than web apps. But the gap is
narrowing.]
