IIRC (and I've only got a windows-based PC in front of me at the moment so I
can't check!) the "-f" means "Force" as opposed to "ask".

I can't see why not, it's not opening up an extra port on the firewall or
granting permissions that will enable buffer overflows etc (that I know of), is
there a reason why you can't do an "sudo" for each command?

I've never really used RSync, so I don't know if it will resync on the entire
folder if the permissions change or if rsync just looks at the folder and says
"this is a new file, please copy it". Others far wiser than me will be able to
answer this one!
