Cilux is a Object Web "Exchange": a peer for, and the reference implementation of, the Object Web.
Cilux is Open Source and written in C. It is intended to be run both client-side and server-side on Linux-based PCs and Ultra-Mobile PCs, including the OpenPandora console, as well as Mobile Internet Devices (MIDs) such as Nokia's upcoming Maemo 5 device. The typical MID specification and APIs aimed for are: at least 320x320 touch screen with OpenGL ES 2.0; GPS, Wifi and 3G; front- and back-facing cameras.
