Is this possible? If so, How?

Virtuemart noob here!

I am upgrading my client to Joomla 2.5 and was considering using virtuemart for a major component of their site.
My question is this.  Is it possible to create multiple stores for each customer?  Here's why I ask...My client has a small customer base (under 100 customers).
These customers have their own catalog of products.  I need a way to ensure that the customer logs in to virtuemart and only views their own products and not others.  Additionally, if that customer searches a product, I can't have other customer products in their results.

Looking forward to an answer to this I hope, not to strange scenario.

frontend only?

then use shoppergroups & assign products to shoppergroups

BACKEND? You mean they sell products?
If so, multivendor , and I dont have advice on this
