omniORB is an Object Request Broker (ORB) which implements version 2.6 of the Common Object Request Broker Architecture (CORBA). It supports the C++ and Python language bindings, is fully multithreaded, uses IIOP as the native transport, and comes complete with a COS Naming Service. omniORB is one of the fastest available C++ ORBs.
sTeam provides a technical platform which allows groups of students, lecturers, and any other groups to construct and arrange their individual and cooperative learning and working space. It consists of an object-oriented server connected to a database, and Web, Java, and other (FTP, SMTP, IRC, etc.) clients. The server is event-driven and manages all user objects as well as the communication between the connected clients. Features that were different from most other cooperation tools is the self-organisation and self-administration by the members within the virtual environment.
ulxmlrpcpp is a library to perform calls via XML-RPC in an object oriented approach. It is possible to create both client and server applications in multithreaded environments. Unlike other implementations, it does not insist on HTTP for transportation, but might also accept other ways (e.g. a simple serial line with a user-defined protocol). For HTTP as a transportation protocol, the following features are supported: cookies, SSL/TLS, proxy, SSL/TLS over a proxy, and chunked transfers. ulxmlrpcpp is also able to transmit data faster with binary XML.
