This is somewhat similar to what we would like to do. If anybody wants to design this for free

or make us a quote feel free (intenetonpoint@hotmail.com)
What we would like to do, is allow the "vendors" in the Pro version of the cart, be able to customize the look of the store. This doesn't have to be done via the admin or vendor management sections, as I can customize templates for each of the vendors.
For example:
The main store:
http://www.domain.com/xcart/store.php
Vendor 1's store:
http://www.domain.com/xcart/store.php?template=vendor1
Vendor 2's store:
http://www.domain.com/xcart/store.php?template=vendor2
Vendor 3's store:
http://www.domain.com/xcart/store.php?template=vendor3
All of the above links would have different template looks to them, though it is only one store, with a central database, one merchant account, etc. We want ONE store with MULTIPLE templates.
The linking doesn't need to be as stated above, as long as the final outcome of multiple templates is accomplished.
This could be further advanced by allowing the vendors to choose which products they want to display within their templates.
