ecommerce product interface for multisite control

we are looking for an interface/plugin that will allow us to control all products on all the sites on our network on multi site

from the main site or from an interface linked to all cast off/minor sites, i want the ability to select which products/categories ect from the MAIN site, download and display on the minor sites databases or front end

so i can quickly select, publish, unpublish and update all products across all sites from the main database in just a few clicks, saving me going through all sites to update products as all is essientiall controlled from one

this should allow me to enter the products details in ‘spin’ or ‘spintax’ to allow each version taken to be different

along with the prdouct ‘control hub’
we would need all sales, invoices, customer details etc to be processed via the main site/database
this is for ease and to keep them all in same place and going through just one payment gateway
this should be done without the customer becoming worried about being redirected or confused
so maybe a plugin that loads each minor sites logo to the corner of each checkout template

anyone know of anything out there like this??????
