Affiliates + ProSites + MarketPress

I have a question about these 3. In order for affiliates to register prosite sign ups, it has to be network activated. I have some service products on the main site with marketpress that i also want to let affiliates earn from referring. What i don't want is to pay out affiliate referrals to other sites in my network.

So, in a multistore network, will someone have their own affiliate links for their own products?
