MarketPress Target Countries Shipping and Downloads

Quick question (hopefully):

Will customers outside "target countries" checked in the MarketPress shipping options tab be prohibited from purchasing digital downloads?

To clarify, we are primarily selling digital downloads in one of the blogs on our network. We are activating MarketPress site-by-site (For future Pro Sites Integration), and have checked only a few common countries on the shipping tab in the MP admin area of that blog. Will customers from countries other than those checked still be able to purchase digital downloads? Or, will they only be blocked from purchasing other non-download products? Just need to know if I should check all the countries or not.

Thanks!
