Transfer rate /= latency. ;-)

Somebody suggested that by burning data onto a CD-ROM and getting 
students to cycle to the other side of Cambridge with the CDs in 
backpacks, you could achieve several GB/s mean transfer rate. Of course, 
the packet latency would be about 25 minutes each way…

(Of course, use DVD-ROM - or BluRay - and it improves even more!)

I wonder - what happens if you combine RFC 1149 with USB flash drives?
