A Question For Rugby Fans

To any Rugby union fans who read this blog, I have a series of question for you.  First a little prelude.  In football, there is a Club World Cup (which I just recently wrote about), a tournament in which the top clubs of each confederation play each other.*  Prior to the Club World Cup was the Intercontinental Cup where champion club of Europe played the champion club of South America.

My question is does Rugby union have anything similar?  My knowledge of Rugby union is faulty, so correct me if I am wrong, but there is the Heineken Cup for European clubs and Super Rugby for regional franchises in South Africa, Australia, and New Zealand.  Is there or was there ever a competition in which the Heineken Cup winner played the Super Rugby winner?  If not were there ever plans?  Are there logistical issues?  Do you think it would capture interest or make money?




*  Confederations roughly correspond to each continent, but there are exceptions, which is why Israel, Kazakhstan, Turkey, Cyprus, Armenia, Azerbaijan, Russia, and Georgia all play in Europe rather than Asia, Australia plays in Asia rather than Oceania, and Guyana, Suriname, and the entirety of Central American play in North America rather than South America.
