Re: So how should one start? What licence?
Even with closed source, you can avoid to bid for a contract if you don't like the origin, but I don't believe you can hinder a reseller to sell your products to whoever they like, as long it's a legal sale not forbidden by law. I'm not sure you can't even refuse a direct sale when requested without a good, legal reason (i.e. a true risk of not being paid) - think about a shop refusing some customers because they don't like something in them....
