Digital BW, The Print

I did a quick search on this topic but didn't find anything, so I 
thought I'd post this suggestion. 

I've participated in print exchanges before and would like to do so 
again. But I think it would be fascinating to see what photographers 
would do with each other's digital files. In other words, let's say 
there are 5 participants. Each makes available a high quality scan 
(via e-mail or ftp, etc.), which is uploaded by the other 4 
participants. The 4 "receivers" then edit the files in Photoshop 
using their own visualization and technique. These finished files are 
then returned to the original photographer, ideally with some notes 
on what was done. The original "senders" can then print the files and 
compare the results if they choose. 

I think this would be a fascinating learning experience from both 
points of view. The sending photographer will almost certainly learn 
new techniques or ways of seeing the image, from the variations 
produced. The receiving photographers also will learn something. I 
think we sometimes get too close to our own images and by practicing 
on the work of others, we somehow will get liberated to experiment 
more. I expect we also learn when we start articulating what we did 
and why, in terms of workflow.

In addition to the above benefits, there are no postage costs and no 
onerous work for whoever coordinates the exchange. If the 
photographers wish to take things further and return the finished 
files as prints, that's up to them. But my real interest is the 
workflow aspect.

What do people think? Any suggestions to refine this and make it more 
interesting or useful?
