With the rise of government surveillance programs, Tox, a FOSS initiative, aims to be an easy to use, all-in-one communication platform that ensures full privacy and secure message delivery. Tox must use UDP simply because hole punching with TCP is not as reliable. However, Tox does use TCP relays as a fallback if it encounters a firewall that prevents UDP hole punching.
Jami is free software for universal communication which respects freedoms and privacy of its users. Its main goal is to provide a communication framework and end-user
applications to make audio or video calls, video conferencing, send text messages and make generic data transfers. It makes this possible via multiple paradigms: a modern decentralized approach using a DHT to find peers or classical centralized SIP as a soft-phone. The domain of usage is not limited to physical users, it also includes integration with connected objects (IoT).
Deskreen is a free desktop app that makes any device with a web browser a second screen over WiFi. Deskreen can be used for mirror entire display to any device that has a web browser.

Kopano Core provides the foundation for groupware messaging enabling clients such as Kopano WebApp, Kopano DeskApp, mobile and sync clients. With its modular architecture, Kopano Core enables the possibility for a variety of setup scenarios, scalable from a very low-powered system to a multi-datacenter setup providing messaging capabilities to tens of thousands of users.
tmate is a instant terminal sharing built on top of tmux. All users see the same terminal content at all time. This is useful for pair programming where two people share the same screen, but have different keyboards. Accessing a terminal session is transparent to clients as they go through the tmate.io servers, acting as a proxy. No authentication setup is required, like setting up ssh keys.
Screensy is a simple screen sharing solution. It consists of two parts, the rendezvous part which runs on the server, and the website part which runs in the user's browser. The rendezvous server is only used for protocol negotiation and discovery of viewers. The video stream is directly sent from the browser of the broadcaster to the browser of each
viewer. All traffic (between rendezvous and browser and between browsers) is encrypted by default.
The OpenTok Screensharing Accelerator Pack provides functionality you can add to your OpenTok applications that enables users to share the screen. This section shows you how to use the accelerator pack. Click here for a list of all OpenTok accelerator packs.
