MultiSite/MultiVendor

[kiki90]

Hello there

I'm not sure if this is the right place where to list my question.. I have looked at this post here:
http://forum.virtuemart.net/index.php?topic=107588.0

And I would like to know if its possible to have virtuemart act as a multisite (as described by the post linked)

basically what I need is this:
One Joomla and one virtuemart with a set of already added categories from the administrator.
The user can login either backend/frontend add add his products to virtuemart
All of the products will be viewed from the frontend having the name of product, price and the name of the shop that particular product was added from.
Each user can only view, add, edit his/her products, while the administrator can have access to everything

Are there any modules/components which can do this?

Thanks
