251764 elgg magento integration

I need a clone of the [login to view URL] site but with a twist. There needs to be an eCommerce component to it. The main thing is the look and feel of [login to view URL] so that current multiply users will feel comfortable. It does not have to be exactly like [login to view URL] but as easy to use and customize as some of the other major social network sites, like facebook. So, basically it's an integration of a social network site and an eCommerce store. Perhaps and integration of elgg or dolphin with magento? Each user should be able to manage their own products on their own subdomain and customize the look and feel of their site with ease, drag and drop panels, change background, etc.
