I always thought the place to make changes would be to de-couple the 
thing that makes rsync/rsyncd full backups slow (the hard-coded addition 
of "--ignore-times" for full runs in lib/Xfer/Rsync.pm) from the other 
things that full backups do.  I haven't needed it yet, but if I did, I'd 
probably try knocking that out except on weekends or maybe once a month 
and then configure for daily full runs and no incrementals.
