I was curious to see if there was the ability to have multiple sellers in the same shopping cart system.  I have a friend who is starting up a business selling items, but eventually, he wants to open that up to others to sell their items on his site while taking a small percentage of the purchase for admin fees (or in some cases, he would allow people to not have to pay the admin fee).  I haven't seen anything specifically that calls this type of setup out, but it seems like it would be a tiered admin access type thing.  This person would have their own login, could add items, costs, etc., but they would only have access to their own reporting and not the entire store.  Hopefully this makes sense.  Just curious if this is built in as is, or if there is a possibility of getting something like that developed.  I really like the system (have checked out the demo extensively), and think this is a good fit for my client, but that was one of the questions that he had.

Thanks, in advance!
