Affiliate for specific product?

Hi. I'm working on a store that Users will add their products to. The User will send the details of their product to the store manager, he will add the product to the store, and when that product sells they get a percentage. We have all of that worked out except we can't figure a way for the User to be able to check the stats of their product sales. One thought we had was to create an affiliate account for each User, and somehow attach their affiliate code to their products only? And they would then be able to log into their affiliate account to view their product stats?

Would something like that be possible, or maybe another suggestion?

Thanks!

Thanks Nicolas, that makes sense, I will pass this info on to the client.

Thanks again.
