> how would I rsync just what has been modified?

If I interpret this question as:
'how would rsync know just what has been modified?'
The answer is: it depends.
rsync will compare timestamps unless you use the --checksum option.
RTFM...

If I interpret this question as:
'how would I know just what rsync has updated?'
You don't, you trust rsync.
I you don't trust rsync (I don't), you can run it twice with the --checksum
option (I do) or you can:
ssh user@box 'cd my-path;find . -type f -exec md5sum "{}" \;|sort' >
/tmp/remote.md5
cd my-path;find . -type f -exec md5sum "{}" \;|sort > /tmp/local.md5
sdiff -s /tmp/remote.md5 /tmp/local.md5
Ang get your banana... :)

Good luck...
ET

PS: Free advice, you can't sue me... :)
