GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
CRest (Client REST) is a lightweight library that simplifies the integration of third party RESTful services into Java applications. CRest is mainly annotation-driven, allowing the developer to focus on the essential aspects of the integration of a REST service, such as the definition of the Java interface that maps the remote REST methods and the data model the interface will deal with. The rest is achieved by annotating a plain Java interface with the relevant information such as the service end-point, the desired timeouts, URL formats, etc. CRest will handle everything else, including HTTP request generation, auto marshalling of the response, and more.
MundoCore is a lightweight and easy-to-use communication middleware to integrate heterogeneous software systems, consisting of services written in different programming languages and running on different operating systems.

OpenMobster is a mobile cloud platform to integrate mobile apps with Cloud services. These services can be anything ranging from your Corporate backend (CRM, ERP, etc.), to consumer Cloud services (Gmail, Facebook, etc). It features Seamless Data Synchronization: synchronizes and manages the life cycle of locally stored data. This data is then automatically/bidirectionally synchronized with the cloud. Push Notifications: app state changes are proactively pushed to an App from the Cloud server. The Push mechanism uses a pure network/socket based approach instead of clunky methodologies like sending SMS alerts or email alerts. The Push notifications happen inside the app's execution environment. In case of iOS, Push is based on the Apple Push Notification Service. Supported platforms: Android and iPhone/iOS.
RoboBrain SDK is a simple, lightweight 2D game engine for Android phones and tablets. It supports OpenGL ES 1.0 Rendering, a custom GameActivity class, a World/Entity system, basic physics and collision detection, animated and static sprites, and support for Multitouch and accelerometer input.
