Ice moving around has not been a problem so far for me and we get a lot of wind. If It was, I would imagine you could just get a heavier duty pipe or sink it further, etc.

Basic idea is the pipe allows a way for the air to vent from beneath the ice so the ice never lifts off the water very much if at all. This should keep the plume in contact with the ice and melt a hole. If it works it'll be a home run for me. A simple solution with no moving parts or unneeded complexity (both are killers on the mountain).
