Turn MarketPress into a multisite catalog

Hello, I'm looking to make a catalog that's available to every single site at a specific level. The catalog will not have an "Add to Cart" function, and thus, will not need any "Checking Out". It will simply be a listing of all products available.

I only want this catalog available to Gold members, (I have two levels, silver and gold).

I am doing this because I want a list of all of the products available on every site in the network, but I don't want to recreate the wheel, simply allowing all sites access to the same catalog is ideal
