psyced is a distributed chat and messaging system based on the Protocol for SYnchronous Conferencing. PSYC is multicast and routed between servers and clients in a scalable and efficient way, but users can also comfortably use IRC clients, telnet, Web chat, WAP, or Jabber to enter the network. psyced also communicates with the network of Jabber/XMPP servers and hosts programmable chat rooms for all of these technologies at once. It also provides gateways to several IRC networks, but unlike IRC, everyone can run a server and be an equal member of the PSYC network. It supports PSYC, XMPP, IRC, TELNET, HTTP, Applet, SMTP, WAP, XML, RSS, and TLS.

SMSTerm is an application that uses the ICQ2000 protocol to present you a shell on your mobile phone which allows you to interact with your computer from any mobile on a GSM network. It runs a shell on a pty, and allows you to directly send commands to the shell through SMS. Minimal authentication is done over SMS before spawning a shell and offering it to the user on the mobile phone. It is very useful for remote administration tasks, or checking out the status of the network, or just to run some small chores on your system while you are away. It uses Expect.pm in the background. SMSTerm also includes a script to send SMS through the ICQ network from the command line to any GSM mobile, and also includes a PHP script to set up a Web->SMS gateway.
