Well put Pascal! The concept of the cloud is the future of parallel and ssi computing. You have the ability of instantiate a cluster in minutess to do your heavy calculations, you pay for bandwidth & processing time. Then when you don't need it you pack up your image & go home... much more cost and time effective than maintaining your own cluster. Any researchers on the list?
