It looks like the vines themselves are not edible, so I would not chance it with gliders since they can chew into bark and trees.
I use wacky wood vines that are Lima roots or manzanita perches that you can buy in the bird section at a pet supply store.
Or you can use branches from trees like apple or crab apple as long as the trees have not been treated with any pesticides, antifungals or fertilizers.
