Cloud in the World.

What does the tech people out there think? Do you think it is possible for all NAS owner to share some of that storage space and create a crowd sourced cloud? For the time being it will just be cloud storage. What happen when NAS get smarter, would a full application stack be possible?

At this point in time I think that it is possible for the applications which are running on PHP. Hmmm, I wonder will there be a NAS that will has it on JVM? A galaxy S2 at the core should be more than sufficient to power one reasonably well. Right?
