I'd suggest putting in a warning if rsync detects a large file (500M?  
1000M?) in its file list.  This should be simple to code and will serve
to let people know that rsync's usually excellent transfer rates might be
suffering a bit because it had to re-checksum the file.

I'd also suggest making the "I had to retransmit the file" message visible
with just "-v", rather than "-vv".

If you all think it's a good idea, but don't want to actually code it, let
me know and I'll build a patch.
