Stamatis Vassiliadis established the SAMOS workshop in the year 2001¿an event which combines his devotion to computer engineering and his pride for Samos, the island where he was born. The quiet and inspiring northern mo- tainside of this Mediterranean island together with his enthusiasm and warmth created a unique atmosphere that made this event so successful. Stamatis V- siliadis passed away on Saturday, April 7, 2007. The research community wants to express its gratitude to him for the creation of the SAMOS workshop, which will not be the same without him. We would like to dedicate this proceedings volume to the memory of Stamatis Vassiliadis. The SAMOS workshop is an international gathering of highly quali?ed - searchers from academia and industry, sharing their ideas during a 3-day lively discussion.Theworkshopmeetingisoneoftwocolocatedevents¿theotherevent being the IC-SAMOS. The workshop is unique in the sense that not only solved research problems are presented and discussed but also (partly) unsolved pr- lems and in-depth topical reviews can be unleashed in the scienti?c arena. C- sequently, the workshop provides the participants with an environment where collaboration rather than competition is fostered.
