JetBrains has a demonstration of this technology on this page. I could only get it to work in IE. Very impressive stuff. Seems like JetBrains has a lot of intentions and infrastructure built up around the GWT Studio to make GWT development easy and fun. Definitely going to have to check this out. The most current EAP, build 5350, has the GWT Studio plugin installed by default.
