It would be if Affiliates integrated with Floating Social. Here is how I would like to see it work:
If a member of a network is logged in and travels to any site across the network, Floating Social (activated across all sites of the network) would be aware of their affiliate ID. Sharing via any social means would quietly include their affiliate info.
