Same trick the pulsar astronomers at Swinburne used to do with Apple 
Xserve RAID boxes taking empty drives from Melbourne to Parkes and 
returning with full drives with data.  These days they have connectivity 
out to the dish thankfully!

This also had an application in HEP in Australia when it was cheaper to 
fly someone to Japan to the KEK collider to recover data on tape than it 
was to ship it over the 'net back to Australian researchers.

All the best,
Chris
