After posting that, I immediately had nagging doubts, so I did a  
quick test on my system.  Here's what I got:

SCP: 5.4 megabytes/second.
HTTP (fetch): 8687 kilobytes/second = 8.48 megabytes/second.

The figures given are self-reported averages over a 2.2 gigabyte  
file.  I did it a couple of times with different files to rule out  
any disk cache effects.  (Although the file is so much bigger than  
available RAM that any cache speed-up would be minimal, anyway.)

So on my system HTTP is actually faster.  However, this might vary  
depending on the software being used (some web browsers seem to  
download slower than others) and the specs of the machines involved.   
My frontend has only a 1 GHz CPU, so SCP encryption overhead hits it  
harder than it would a faster system.
