The complexities of dealing with properly invoking rsync externally
could well require more code and be considerably more fragile than
passing the data through the existing SR connection; particularly
since to get the full benefits of rsync you need to be dealing with
a daemon which has the appropriate modules configured -- the
location of which you wouldn't easily know.
If we were talking about re-implementing rsync, or doing more than a
rough approximation, kinda, of 5% of what rsync does, I'd be with
you.
