Does this exist?

I am looking for a shopping cart software that has all the features of 1shoppingcart but where you can buy the script. I want the script hosted on my server.

Main features I am looking for:
1. Ability for people to sell their digital products on my website
2. Recurring paid membership for sellers
3. Free membership for buyers
4. Affiliate system where if I charge a $10 membership for sellers to join and if someone refers them to my website and they join, I want that person to receive $5 a month as long as them member continues paying.

Anyone know of something like this?

I think 1shoppingcart.com script does but you have to host with them. Any ideas?

 

I think amember could help you .. It works with a variety of payment processors as well ..

 

But what shopping carts does it integrate with?

 

Anybody???
