register esa.ch ?

Dear colleagues, I have got a request from the company "Einkaufsgenossenschaft des Schweizer- ischen Autogewerbeverbands" to register the domain esa.ch. ESA is the registered name of this company that appears also on their letters. I have called their attention to the fact, that esa stands for European Space Agency in different European countries (e.g. esa.de, esa.es, esa.nl ) and that therfore it is not wise to register esa.ch for something completely different. But they insist on this name. Would you register it? Regards, Willi Huber
