This is something i'm really looking forward to:

Controlling the camera without touching it even over a long distance is amazing!
Which means I can control the camera from a warm sleeping bag on a remote timelapse shoot! This a very cool product!
Really cool feature to have for those one-off shots, and surprisingly it works very well (live view is quite responsive)!
I wonder what else can be done through the 6D's WIFI. Would be cool for example if there could be a way to upload directly to different image services (flickr, facebook, etc.).
