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.
The Interreality project is a collection of Open Source, Free Software projects based on the Virtual Object System (VOS) platform. The goal is to develop a free and open platform for multi-user 3D virtual reality games, applications, and interactive, collaborative 3D virtual spaces. VOS is a powerful and generic network object framework designed to support a variety of high-performance applications. It is the basis for Ter'Angreal, a general-purpose browser application for entering and participating in 3D worlds.
Pakt is an XML abstraction layer for GObjects. It maintains a server-side tree of glib-like (Gtk, Gnome, etc) objects and provides access methods to manipulate the same (and thereby the running 'application'). Its primary use is to publish GStreamer pipelines, enabling connected clients to monitor and change the element's parameters and the pipeline's structure.
Wiaflos Accounting is an attempt to create a multi-platform server-client based accounting system. The goal is to have a central accounting engine which can either run on a dedicated server or on the same PC as the client interface. A SOAP API allows for the easy writing of GUI or Web interfaces or for tying into in-house systems. It is intended to be useful for everyone from single-person organizations to multinational corporate entities.
