Laszlo Systems announced the beta release of its latest product (or should I say framework) to help make AJAX/RIA development easier. Its called “Laszlo Webtop” and its aim is to help do two things - (1) provide the infrastructure to create a desktop on the web(or should I call it Portal 3.0) and (2) continue the effort of providing server side infrastructure for Java developers to utilize the tools, libraries and container services that already work well for them.
This is built on OpenLaszlo, but is a commercial offering. Laszlo has what they call an early access program to testdrive this framework. So if you are interested, you would have to request for it through their website - www.laszlosystems.com.
