Multiple Sellers

Hello,
Is it possible to setup ZenCart in such a way that multiple people can create accounts where they can sell their own stuff? For example, Admin gives User A a seller account. User A can upload his stuff to the store's server and it appears in the Admin's store. User A then gets all of the profits from the sale and can put his own products on sale. One way I thought of doing this was making people like User A an admin and then restricting their privileges, but I don't see any way to do something like that. Is it even possible with ZenCart?

In short, no. Zencart can't really be used as a 'mall' sort of operation.

There is a MultiSite Module but, it only allows for a single admin section.

You may be able to combine it with the Admin Profiles module.
