So many rice questions, Blouen. In America at least, sticky rice is only known by people who know a lot about Asian foods. They call it sticky rice, too. As far as I know it hasn't got another name.
And in answer to your other question, we don't have a special pot for cooking rice. I believe you can buy those electric rice cookers here, but they're not a must-have item for the American kitchen by any means (except in Hawaii!) I think if a fancy cooking store were to begin selling calderas, they would probably call them calderas. I've seen various ethnic cooking utensils marketed by their foreign names---the Moroccan tagine springs to mind. And maybe a wok, although I have no idea if that's what the Chinese really call it :)
