Wow, a book with all the images, sounds like fun too.
I have a similar project going on here in Germany as part of a German Nikon Forum. Although most of the members in this forum use digital cameras there are at least enough people that, when I announced the idea within 23 hours I had 37 people on the project, enough to fill a film.
Now my little FM-2 is on its way through Germany with some postal deliveries and some personal meet-up to give the camera to the next participant. It started its way 18 month ago and probably needs around 3 months more.
Once the camera is home again I am going to develop the film and make enlargements of all images which I put together into an album which itself is going the same way back as the camera.
