PerSys 2006 PC Co-chairs' Message.

We welcome our workshop attendees to a very interesting collection of discussions. We received many papers and had to limit the acceptance rate to 40those papers submitted. The papers cover a range of topics from Infrastructure, Service Discovery, Personalization, Environments, Security, Privacy, to Wireless and Sensor Networks showing the scope of interests and activities represented by the PerSys participants. We would like to thank everyone who submitted a paper and believe you will all find the presentations and discussions stimulating and worthwhile. The reviewers of the papers have done a terrific job in helping authors prepare better final papers and deserve special thanks for completing the job promptly. Last, we would like to thank the organizers of the conference a sincere thanks for the hard work they have put in to providing us with the opportunity to gather, present, listen, and discuss our research.
