Hi guys, i am just releasing SimpleDDS.
In order to connect into ROS world i had to implement a DDS support (Publisher/subscriber).
For achieving this i did MetaDDS, a library that defines basic objects, announcements, event related mechanisms and data encoding formats, and on top of it SimpleDDS, which is ROS based.
SimpleDDS Has a package of examples highly commented for learning how to use it.
The comments are also in the Github wiki, as wiki pages:

I haven't heard of DDS, but this seems really significant! From wikipedia... "DDS addresses the needs of applications like financial trading, air-traffic control, smart grid management, and other Big data applications. The standard is used in applications such as smartphone operating systems,[1] transportation systems and vehicles,[2] software-defined radio, and by healthcare providers." This could be a nice lead into these application domains. If this got to a sufficient level of features, maybe Santiago could even be sponsored to attend an interoperability meeting? "DDS vendors participated in _Interoperability demonstrations_ at the Object Management Group (OMG) Spring Technical Meeting.[7] During the demo, each vendor publishes and subscribes to each other's topics using a test suite called the Shapes Demo." Such might be a good place to network and demo general use of Pharo. cheers -ben
