474451 Install Multi User/shop for OSCommerce

I am almost positive there is a free plugin that allows for multiple people to sell on one domain using OSCommerce. If this is the case I need this installed. I am not looking for a custom plugin but a preexisting one. If you are familiar with oscommerce and know of a plugin then please respond. Again I will need it installed. This should not be a hard task so anything over 15 I am ignoring.
