1 PP Pro with s2 on multisite

Hey Guys, so in our recent development, we’ve found the need to convert our site to a multisite blog farm. The main purpose is to sell access to content to the specific child blogs sharing a buddypress install. I understand we’d need to configure s2member per child site with the permissions ect pertaining to the specific blog. I was wondering how this would work with one PayPal Pro account. In essence we’d be handling all transactions for these separate sites. Is this possible? Also, with the Buddypress constant define( ‘BP_ENABLE_MULTIBLOG’, true ); which allows sharing the home buddypress install with the sites across the sites, will a user from the home blog be able to subscribe to paid content on any of the child sites? In my head, users will be able to navigate to these child sites, they would then be able to purchase the content specific to that site and visit the site at will for the content from the buddypress profile. Does this make sense and will it work? Lol.
