"Non commercial" does not mean "non profit", the bare act of selling something is commercial even if you loose money. I think most people who put their contents under a non commercial licence want to prevent big profits realized by big, bad capitalist companies and do not realize that the nc licence is much more restrictive than that.
Went to Nouméa last November, came back from Hobart last week. That means going through 7 different airports (Geneva, Frankfurt, Singapore, Sydney and then Hobart, Sydney again, Bangkok and London). The only places where I was annoyed about my luggage or something were Frankfurt and London. Yes, 2 european airports. As a Swiss-French national, that does not make me feel proud of it.
