this is more or less the general gist of it.
a good example to explain the possible use cases is Gmail.
currently its GUI is rendered inside a browser on the client side via a
javascript library. the end goal of the concept is to enable to /easily/
replace that javascript code (generated from Java by their toolkit...)
with a native client GUI made with DWT.
you press a link on the Gmail site and presto the native client is
downloaded and deployed locally so you can now enjoy a real UI that is
not limited to HTML just like any other desktop application on your
Just like Java web start only without requiring a huge JVM and which
actually always works, just like adobe AIR only not proprietary and with
the right click working, like microsoft's ClickOnce only cross platform
and open. And it'll give you a /native/ look and feel thanks to DWT!

DWT is a major part here since it provides a very clean API, D itself
provides for performance and ability to provide bindings for other
languages through its linkage with C (important for interoperability).

if you want to discuss this concept further I'll be happy to discuss
more fine-grained details.
