Hipp, a Croatian Software-Manager contacted me:
Hi, I am from Navigo-Sistem, we are distributers for Garmin in Croatia. We work on cartography and we want to link your Anchorages Map from our iPhone App. You will be mentioned in our application Copyright section, would that be okay for you?
Yes, of course it would!!!
And as the result, my Map is finally available via "Adria Marine" iPhone app, see details here.
