I would like to see communal settings, where more than one species is present in a large enclosure. I would usually think against it, but I'd think you'd have the resources and knowledge at hand to pull off something I've personally never seen in person before... Wait, scratch that. I had gone to an alligator farm last summer and they had a setup with a blood python and 2 other species (only remember the one) in a VERY spacious enclosure. What was interesting about it though was that each snake occupied a different niche and had plenty of room and hiding opportunities so that they probably rarely intermingled. But by spacious, I meant it was about the size of my bedroom kinda spacious. Something like that would be nice to see.
Edit:
Did a lot of searching on the internet for a picture of the enclosure... And I think my memory had exaggerated the size of the enclosure ^.^ It's the big one on the left, best pic I could find
