I was able to get FlexSpaces UI for document management with Adobe LiveCycle Content Services ES integrated with LiveCycle Workspace UI for starting processes/forms/task-lists. The workspace start process, to-do, and tracking are in tabs. The workspace preferences, messages, help are available from menus. It works on Flex+Browser. Also will SSO from/to other LC apps. (I can’t make this available as open source).
For an integration of FlexSpaces+AIR with Workspace, getting PDF Form controlling code to work in Flex+AIR looks challenging. I could also create some Workspace pods for FlexibleShare (although FlexibleShare is Flex+AIR currently, could also do a +Browser version)
