ContentWatch has begun selling the Mac version of Net Nanny 2.0, substantially upgrading its blocking and surveillance software. Users can prevent children from accessing various applications or websites, either on a wholesale basis or for specific durations only. Multiple profiles can be created to allow mature kids greater freedom.

The v2.0 release introduces chat and instant message monitoring, which can be used to send administrator alerts whenever particular keywords arise. Filters have meanwhile been expanded to cover FTP, SFTP and SSL traffic, as well as DVDs according to rating, and social networking sites like MySpace and Facebook. Some 40 multiplayer games can be blocked, including Quake and World of WarCraft.

Net Nanny costs $40 in an individual license; a $20 surcharge exists for each additional computer in a household.
