x10dev provides a /dev interface to an X10 network through a combination of Linux kernel modules and daemons. It is intended to provide a standard interface and syntax to shell script utilities (such as cat and echo), Perl scripts, C programs, or Java programs so that everything from a quick hack to a more advanced program can manipulate the X10 devices in an automated home regardless of the transceiver used. Its simplest use is with shell scripts (examples of which are provided in the package). Currently the project supports the 3 X10 transceivers (PowerLinc Serial, PowerLinc USB, and CM11A).
Project Utgard is a sub-project of the openSCADA project. It's focused on creating a completely Java and open source OPC interface for the openSCADA project. In order to create clean interfaces between both worlds, a separate project was created which only covers OPC specific functionality which can also be used outside openSCADA to create OPC software.
