Cocomo is a Platform as a Service that allows Flex developers to easily add real-time social capabilities into their RIA (rich Internet applications).

Comprised of both Flex-based client components and a hosted services infrastructure, Cocomo allows you to build real-time, multi-user applications with Flex in less time than ever before. And because Acrobat.com hosts the service, issues like deployment, maintenance, and scalability are taken care of for you.

Features of the Cocomo beta includes, VoIP Audio, Webcam Video, Chat, Multi-User Whiteboards, Real-Time File Sharing, User Management, Roles and Permissions and Robust Data Messaging. To get access to the public beta of Cocomo service and Cocomo SDK, you just need to create a developer account in Adobe.
