While it's not Phorm related I must say I was impressed when I installed the Nintendo Channel on my Wii this morning. The channel gives you info, gameplay video's, DS Game demo downloads, the ability to leave feedback for games and general Nintendo related news.
During set up it asked me if I wanted to opt in or opt out of receiving info from game companies to my Wii Message board and sharing my gaming habits with Nintendo, it wouldn't proceed until I'd made a choice on both, it also informed me that by doing so I was revealing information etc.
Simple, but well implemented. Info on the opt in/out system on the channel can be found
HERE with the more info on the info shared with Nintendo
