I could see this being useful at some point in the future with something like 
nasa whirlwind and large sat imagery databases.  Currently I suspect such users 
of massive datasets are quite happy managing their own multi terabyte 
collections of various data provided from various sources.  But I suppose if you 
keep in mind the 1.44MB floppy -> $10 1GB microsd-usb path, you also should keep 
in mind that we aren't so far away from a 10T laptop, perhaps holding 1T of 
public sat imagery displayable via whirlwind, just because it's cool and free. 
(except for cheney's house of course).  And probably by that time, if possible, 
people would enjoy managing their various sat imagery layers with the same 
package management tool as the rest of their system.

And of course then their are video games with datasets that large, or perhaps 
just depending on the ubiquitous free nasa whirlwind datasets.

But of course then someone will make a video game that simulates terrorism, or 
even global thermonuclear war, and the feds will have to crack down on this new 
'virtual terrorism training ground' ;)
