Where Wi-Fi and gaming goes, cloud security comes tumbling after, and so weirdly it is with Nintendo's DSi games console.
It's probably not why kids and kidults buy these devices, but the DS, DS Lite and DSi all have the ability to play online games through a Wi-Fi connection. The browser (free for the latest hardware) is based on Opera although the experience it brings has not exactly had rave reviews.
The interesting bit is that all the traffic from the DSi eventually runs through Nintendo's own routers and is heavily filtered for "inappropriate content", which presumably stops anyone daft enough to risk the slow connection from visiting dodgy websites.
We understand that the hardware used is unified threat management (UTM) kit from German company Astaro and is run on cloud service lines, a fascinating early mainstream use of such technology.
So there you have it, Nintendo, pioneer of cloud security.
