Actually, what you described is *exactly* cloud storage.  And the CFO 
would love (generally) to pay for it.  Add whatever capacity you need, 
and pay for it ... only when you need it.  Lowers the cost per TB or per 
GB ... however you want to view it.  Your cost to run 1TB includes 
power, cooling, space, etc.  Your cost to increment this costs whatever 
quantum of storage you currently pay in whatever size you pay for it. 
What if, rather than in large "kerchunk" amounts (with gleeful sales 
critters rubbing hands together), it was in effectively whatever size 
amount you needed?

Without turning this into a commercial, we are working with a few folks 
in this regime.  Anyone interested in this stuff, bug me offline.

Do remember, TANSTAAFL though ... you have to pay the storage loaded 
cost, the bandwidth costs and latency to get data.

I have a feeling, if the governments really invest in infrastructure 
that this might be much less of an issue going forward ...
