To take an example, I know of a local group doing work at CERN. Apparently 
they are participating in experiments that generate around 1TB a day of data 
(no idea if that's compressed/uncompressed or how compressible it would be).

At the standard AARNET rate for international traffic of AU$22.50 per gig 
that's over $22,000 dollars a day if you wanted to pull that back over the 
'net (assuming sufficient bandwidth to be able to do that).  It then becomes 
obvious why they choose to fly it back with them. :-)
