DataManager is a library that provides a shared memory pool to allocate buffers from. It includes the necessary things to build servers which regulary produce data and provide them via ringbuffers to clients. It includes the common framework to have locking and various access methods. The use generally boils down to simple get()s and put()s. This project is no longer under active development.
JSX serializes Java objects to XML. You can persist objects, evolve them, and send them over the network and between applications. Your object data becomes human-readable and human-writable. You can test it, search it, profile it, audit it, and edit it with ordinary text and XML tools. JSX handles all POJOs and also all classes that require Java's own object serialization.
PyORBit is a Python binding for the ORBit2 CORBA ORB. It was developped to suit the needs of the bonobo bindings in GNOME-Python, but is usable for other purposes as well. It aims to follow the standard Python language mapping for CORBA. It can generate stubs at runtime from typelibs, IDL files, or by introspecting remote objects using ORBit2's IModule typelib capabilities.
Twisted is an event-based framework for Internet applications. It includes a Web server, an SMTP/POP3 server, a telnet server, an SSH server, an IRC server, a DNS server, a generic client/server pair for remote object access (Perspective Broker), and APIs for creating new protocols. It supports integration with GTK+, GTK+ 2, Qt, Tkinter, wxPython, Mac OS X (PyObjC) and Win32 event loops. It also supports TCP, SSL and TLS, UDP, Unix sockets, multicast, and serial ports. Supported protocols include HTTP, FTP, SMTP, POP3, IMAP, TOC, OSCAR (AIM and ICQ), SSH, DNS, IRC, NNTP, Jabber, SOCKSv4, Telnet, SIP (for VoIP), and XML-RPC and SOAP using external packages. Most protocols are supported as both servers and clients.
