How would the GPS function on the 7D work? Do you need some subscription service with a separate piece of hardware? I'm intrigued by this since I love using Flickr's Geotagging feature (roaming local maps).
It seems like the new wifi adapter has the ability to communicate via bluetooth to compatible GPS devices.
No subscription necessary. The subscription fees cell phones companies charge are there because, well, you don't really have much other choice so they can.
GPS is simply a passive receiver, listening in to the transmissions made by satellites in space. It can triangulate its position simply by seeing how far away the satellites are and thus figure out its lat/long. Then just put these coordinates into the EXIF and you're done. No need for a subscription.
With cell phones, perhaps they charge for accessing the mapping and navigation abilities, but that's like google maps charging for their services. GPS tells you where you are. The mapping software, be it embedded in a GPS receiver that you carry around in your car or downloaded over the cell towers, is a totally independent component of GPS navigation.
