Thanks guys for your advice. It appears all (including guys at DNF and a trademark consultant) agree. I'm off to godaddy to deregister googlecasts.com. Thanks keith for your very constructive advice. Will consider it. But perhaps we should look afresh at these TM issues. If not checked, we may have a few mega cooporations owning almost anything. To me, I think this stiflles competition and creativity and encourages monopoly and arm-twisting tactics. See, I have surrendered even before google comes after me? This in itself speaks volumes as to the future of domains business. Thanks.
