Emacspeak is the first full-fledged speech output system that will allow someone who cannot see to work directly on a UNIX system. Emacspeak is built on top of Emacs.

Mpserv is an architecture for playing MP3s distributed throughout a LAN or high-speed WAN. The core is the server which houses a database of song titles available through the network. Clients connect to this server and request songs to be played on the stereo connected to the server machine. The modular design allows for third party clients to be created with any interface. Included is a ripper/encoder for adding your music to the available database of titles. A sample client is also provided, written in perl/gtk.
