much! Last but not least we would like to thank Manfred Reitenspiess who has been the guiding force behind ISAS and the Service Availability Forum. I hope that the attendees enjoyed the ?nal program, enjoyed the presen- tions, got involved in the discussions, struck up new friendships, and got ins- ration for contributions to the next year's symposium which will be hosted by KimmoRaatikainen,UniversityofHelsinkiandFrancisTamofNokiainHelsinki during May 15-16, 2006.
