Thanks, this was indeed helpful.  Performance was much better, so based 
on this I decided to try it with the actual cygwin 1.7 beta release. 
The last thing I used was deltacopy, so I copied the cygwin 1.7 binaries 
and libraries over into the deltacopy directory and that worked as well. 
  Initial tests show 20-30MB/s instead of 5MB/s -- this still isn't 
anywhere near the performance the machine is capable of, but I am much 
happier.  (For one thing, the cygwin rsync is 3.0.5 and so is the 
BackupPC server, so checksums and deltas are much more efficient now.)

That improvement, coupled with the realization that I can treat each 
large area on a client as a separate "client" that can go 
simultaneously, makes this more than viable.

If anyone wants to try the exact deltacopy/cygwin binaries I'm using, I 
put them online at ftp://ftp.oldskool.org/pub/misc/DeltaCopy.rar.

I didn't know about this limitation, but thankfully have it off on all 
of my machines since I attempted smb sharing first.  What snags did you 
run into?
