Growing mounted orchids

Does anyone have experience with growing Phalaenopsis orchids mounted on driftwood or other materials? I have grown them and Cattleya, in pots but want to plant some in a more natural looking way. It's hard to find good information, mostly just recommendations on, use this material or that material. I'm more interested in understanding exactly what they need, If I know that, I can figure out what material to use.

I remember seeing them in Hawaii where the roots adhered to a tree trunk and ran for several feet, completely exposed to the air but in an environment where they rarely, if ever, dried out. I'm thinking what they really need is just something to hold on to and to always be moist, but not wet as can happen when grown in pots.

Here (Brazil) we often see them tied onto shady parts of trees with a bit of an old kitchen sponge along the roots. I was just in a park the other day where they had done that on every tree, it was really cute. This was, however, right near a pond where due to temperature fluctuations there is a lot of morning mist for most of the year. I think if you can commit to spraying them every so often they'd do even better.
The "more upmarket" way of doing it usually involves coco coir, which can hold a bit of water. I don't have firsthand experience, as I'm more of an edible plant sort of person, but they seem to be nearly everywhere around here so it can't be that hard.

As a kid, my family went to Fisheating Creek to see the cypress knees.  I remember the trees were loaded with orchids.

Here is an article from the University of Florida about how to grow orchids in trees:
