I'd love to introduce new big application which uses GWT as a client.

It is till in alpha stage but already gives some figures concerning
what can be done using such powerfull tool as GWT.

Project Kaiser™ provides (when ready) the following functionality
-Project Management (unlimited projects hierarchy)
-Issue tracking
-Forums
-Documentation management
-Content management
