I had this idea several years ago. What stopped me going forward was a feeling I couldn't make the game spy-like enough to be as fun as I'd like. There are practical limitations to the real world vs. virtual world as some comments already point out -- potential legality/abuse issues etc. Although I thought I could push some of those bounds as much as possible I still couldn't envision how to keep gameplay new and interesting.
I'm glad to see this concept going forward! I would be in, except I don't know how interesting it could be considering the practical limitations as I saw them. From your description I imagine something like: Agent A hides Object along a Mountain Trail where Agent B must find and recover it. That does sound like it could be a fun activity to get fresh air and exercise, but would get old pretty quick in terms of fun factor for a real spy-like experience. I'm pretty sure there would be more in store for the game than that, but how much more is the question...
