I recently discovered Direct Web Remoting.
DWR is a framework wich makes it easy to call serverside code from the client side and allows you to do all kind of cool things. Even though it is still impossible to push information from the server to the client this allows you to build a more rich interface.

for example, if you wanted to update a record in the database through a form, this technology allows you to verify if the new data can be inserted or if the record has been updated by another user without the need to leave the page.
Another example is Google Suggest which provides a list with possible search terms and the amount of results while you type.
