I would like to see Aye-ayes in an outdoor, duirnal exhibit. There are many 'nocturnal' smaller mammal species that zoos are starting to exhibit in enclosures with natural day/moonlight and access to fresh air.
Jersey did have a single Aye-aye in an outdoor enclosure. Probably still has, though I don't know for certain. Of course, more and more zoos are keeping fruit bats in outdoor enclosures. Much as I love traditional nocturnal houses, I do wonder whether the animals wouldn't love the occasional shower of rain.
