I've just checked the rsync sources and rsync appends the host name to
the command given with -e. I don't see a way to add arguments after the
hostname.

I was wondering why you'd need '[something with -e and and stuff]' for
the ssh command to rsync, as I don't know parallel's internals. I would
have expected that rsync is used to transfer the files (with an ssh that
does not need '--' or '[something with -e and and stuff]') and then a
separate ssh command starts the remote command (which would need the '--').

That's a no-go.
