You can do this with your firewall rules or by using .htaccess. You can also force SSL connections, which would protect against MITM attacks on a cleartext session. (You can also require SSL and secure auth for the db and restrict access by IP using the format username@fqdn, but you stated that you're not comfortable depending *only* upon mysql's security capabilities.) However, I would suggest that you provide, as you suggest, a separate instance of mysql just for this client as well. If they screw up the instance they won't affect other customers. To run a separate instance, I would suggest using different names for the binaries, conf files and datadir. This can be easily done using symlinks; e.g. mysql and mysql-special. Then copy the startup script in /usr/local/etc/rc.d/, rename it to mysql-special and edit it to change all references to the newly-named instance. Use a my-special.cnf file for the special instance and reference it in /etc/rc.conf using mysql_args=.
