We released the first version 0.1 of Meilix System Lock. It is an application that can lock or “freeze” your system.
The application is based on Ofris, but it offers more features like a simple graphic interface to lock or unlock the system. Main developer is Hon Nguyen (Vanhonit) from Vietnam, who started the tool as part of his Google Summer of Code project for FOSSASIA.
The sourcecode is here on github: https://github.com/meilix/systemlock
