Rob works in the embedded linux area, through his company Codethink Ltd. He’s been known to co-maintain the D-Bus GLib bingings and help make HAL suitable for embedded handheld systems. He was a cofounder of the Telepathy and Farsight projects, and still takes interest in the messaging, VoIP and collaborative technologies area.
He’s currently working on using D-Bus for assistive technologies, making Tinymail do some funky low-bandwidth low-latency things and some crack distributed revisioning file system ideas.
