@ MW Design: I have never seen problems in an InDesign file if people have used linked native AI files here in the forum, but a lot of problems (fine white lines, wrong background, etc.) when they use EPS. So it is really not a good idea to entrust people to use EPS.
I know that reasons exist to use EPS. But those reasons are not found in InDesign, more in older applications or plotters. But here we are in the InDesign forum, and I give answers appropriate to InDesign.
I would not recommend to give away an open InDesign file, even to another country where they are not aware of local situations. But your example with India is outside InDesign even if a lot of InDesign components comes from India. (In my experience the people of India are more aware to modern techniques as Yesterday people from other countries.)
