I see that there are good points to keeping them separate. I just dont under stand the people that say "you should not do this because, it stresses the snake, cannibalism....." Does any one really know how many cases there have been of cannibalism in a captive setting where both snakes where being feed well? I bet there are more cases of them found living together in the wild then there are of them eating each other in captivity.
Like some one said in an other post the OP asked for views on keeping them together. I think if care is taken in setting things up right it is really up the the owner. If you find some runny poo but one in a QT and see which one is sick. Keeping them together is prob more work, but is some one is willing to put in the time to make a nice home I say more power to them. I think that is better then the people who put them in a tube with paper bedding because it is easier for the owner. My snakes will have plenty of places to hide and plenty of places to crawl around if they please and they will be in the same display tank. I also plan on having a QT standing by if I need it.
