Can I use marketpress as a kind of marketplace?

Hello,

we are creating a new indie book community. Indie authors with appropriate permissions should be able to upload their ebooks into a shop. Marketpress looks very impressing. Maybe its the solution for us.

But there is one problem and I could not find an answer now. Let's say

* Author Carl uploads his ebook to the shop
* The ebook costs 4 €.
* The customer puts the ebook into the cart and pays 4 €
* Now 4€ - 1€ commission = 3€ are transferred to Carl
* 1 € commission remains for the shop owner.

Is that possible with marketpress?

Thank you very much for a short reply.

Best regards

Helmut
