at the distributed virtual Program Committee meeting. Each paper's review recomm- dationswere carefully checkedfor consistency; in many instances, the Vice Chairs read the papers themselves when the reviews did not seem suf?cient to make a decision. Throughout the reviewing process, I received a tremendous amount of help and advice from General Co-chair Manish Parashar, Steering Chair Viktor Prasanna, and last year's Program Chair Srinivas Aluru; I am very grateful to them. My thanks also go to the Publications Chair Sushil Prasad for his outstanding efforts in putting the proceedings together. Finally, I thank all the authors for their contributions to a hi- quality technical program. I wish all the attendees a very enjoyable and informative meeting. December 2008 P.
