I have a question about this module and I do apologize if this has been answered before.

Can this module be used to "link" multi-sites that are not hosted on the same server and have their own database?

If not, can this be achieved?

When a buyer purchases from more than one store and checks out, what happens with the payment? For example. The person pays using PayPal. Both the stores the buyer shopped on have PayPal accounts set up. Does each store automatically receive their portion of the sales or does that have to be worked out manually by the store owners?

Thank you so much for time answering my questions!
