Out of curiosity maybe or general interest but I find that all this big push to "Cloud" computing and clustering lately has still been missing something. All the different cloud computing systems out there seem to all be very much application based. Like running clustered apache setups that allow resources to be dynamically reassigned between users of the system. Now this isn't bad per say, but it is missing the point by a bit. Not saying that the idea is bad or offering services in a cloud is off, just incomplete.
