Join opencart with opencart

Hi there! I explain my question: I've a shop (Opencart 1.5.4.1) where I have to sell some products A but I've to show others products B also. Products B are not selling online. I thougt to build another shop identic to the first . In the first you can buy on line, in the 2nd you can just see products and contact to know where buy it (in a real shop). I would like to registered customers at the first site maintaining the registration in the second.
Not a registration in 1st and another registration in 2d. Just one registration for both sites.
The question is: is there something like a bridge to join Opencart to Opencart?
Or: have you another idea to solve my problem?
Thank you so much.
P.S. I can pay this work if there's a programmer who want to help me.

I can help you with that I sent you a PM, so please check it.

Very useful and easy way to solve my problem
Your extension works very fine, do you think it's working as well on mobile http://www.opencart.com/index.php?route ... =framework ? I've send you an e-mail, but you didn't answer to me: maybe it's lost
