Well, that would indeed be nice. I have a similar "request" : When
doing some testing with csync2 and some big files, I ran into two
issues :

1) It seems that for mode or ownership changes, csync2 re-transfers the
entire file instead of just changing the mode or ownership information.
This is undetectable for small configuration files, but is a severe
performance impact with multi GB files.

2) It seems that all files being transferred are first copied to /tmp
then moved in-place. This is problematic for various reasons when the
final destination is on a different partition :
 - If /tmp does not have enough space for the file, things fail.
 - Moving the file at the end of the transfer takes more time.

These are two aspects of csync2 which, if "fixed", would make it work
much better in the environments where I use it ;-)
