I've had it happen, mainly on accident. I had a rock covered in zoanthids leaning against my back wall and slowly the started to creep up the wall.
I've glued palys onto the wall a few times and had luck with them growing as well. I've definitely noticed that zoanthids and palys grew slower for me on the tank glass than on live rock.

i think it would be awesome to have a wall covered in different zoas and palys..i wanna work on that
That is a cool idea.. I would love to see a completed wall with them...
I'm not a fan of dosing iodine. A good quality salt nix combined with regular water changes should be enough iodine for zoanthids. Dosing iodine can be dangerous, there is a fine line as to how much can be used. Too much (and it doesn't take much) and you'll kill inverts and corals.
