   Hello all,
   I've got a "working" solution now.  I put working in quotes because I'm
   seeing similar dismal performance stats to your script (I also have ~
   400 KB/s DSL connection).  The problem appears to be with the overhead
   of sending and receiving all of the ~ 100 byte requests to both get the
   MD5 signatures and to get the files themselves (large files transfer
   *very* quickly and I'm not using poll() to check if there's data to be
   read on the socket).
   I've got two bugs left to squash and I'll post the source code for
   everyone to review.
   I know you can issue more that one command at a time and my next hurdle
   will be working on speeding things up by combining requests for all
   files in each folder instead of issuing one request for each file.
