Can you list "new" products that you have multiple quantities of? This would open up cheap product propagation to channels for tiny businesses that want to sell homemade things and don't have the time to post to multiple channels. I'm assuming also that you are using one account for EBay to sell everyone's things since you said no need for Ebay API.
