Thanks for the info. I really want to start a project like this. That Film for Classics website doesnt seem to work to well, the Products page doesnt work.
Last time I checked you had to scroll down to the bottom of the page to see anything. Not a good site, but I understand the folks that run the place are OK. I haven't bought anything from them myself.
The 122 film sounds interesting but I have a couple of questions:
1) Development: would you have to manually dip & dunk the film - or does one just assume they'll send it back to Film for Classics to develop it? It's not going to fit in your regular roll film tank, and Walgreens definitely isn't going to deal with it.
2) Enlargement: it would seem that your choices would be to scan it, to make a contact print, or to cut/mask a film holder for your enlarger -it would have to be a 5x7 to get all of it.
Personally, I'd use 120 and make panoramas as Mr. Morange suggested. I've heard of simply inserting plastic wall anchors into the ends of a 120 spool to make it fit. You have to find a wall anchor with a hole about the same size as the "posts" in the camera.
