The ReadyNAS support page for ReadyNAS Remote does not have a link for the Lion-compatible utility. Then, after locating the Lion version on the Downloads page, installing it functions only so far as installing the Mac utility. No setup wizard appears. Nothing. Creating a user account with ReadyNAS Remote is impossible. The instructions dictate that after installing the utility, a configuration wizard will automagically appear. No such thing appears. If you didn't post the URL for the ReadyNAS Remote page for creating a new user account, there would be no way for a user to get ReadyNAS Remote working.
This issue STILL is not fixed either in the installer or the links on the support page.
