I grabbed a copy of the Touch and Farber paper cited earlier in this 
thread, which seemed to deal with  FTP. This described a pre-send selection
algorithm of sending everything in the currently selected directory. The 
Boston University system used a simple 1-level probablistic model to pick 
the best candidates for pre-send, and used fare less extra bandwidth, 
though with a higher probablity of a cache-miss. There's lots of stuff to 
tune with speculation.
