A big issue with glass aquariums is humidity. If it's a snake that needs higher humidity levels, then you may have problems. Also, you don't need to feed your snake in a different container. This is an outdated method that many people and breeders no longer do because you should not bother a snake after feeding it. It is more likely to regurgitate its food or bite you.
First of all, snakes don't hear, so I don't know how they can hear the cage opening. By assuming that they learn that their cage opening means they are going to get fed and will bite is no different than if they learned that the cage opening means they're gonna be moved to the other cage, which would also get a feeding response. I keep and breed several species of pythons and boas, all of which are fed in their own cage. I have not been bit in years. Just make sure you let the snake know you're there and don't stick your hand in if you've handled rodents. They know the difference.
I did a quick search on the myth of feeding in a separate container. Here's a link. There are also many other pages that support what I said above.
