Stupid idea. Trees grow and thus move over time. They're not stable
long enough for construction purposes.

Mark a spot 4-5 feet up on a tree, 20 years later it will still be 4-5
feet from the ground.

But won't the diameter, where you marked, be a lot greater? Anything
tied to the tree will get buried in the wood. Even if you leave 'room
for expansion', this may still happen. A tight loop, buried in the wood,
will also choke off the sap, and possibly kill the part of the tree
above.

Ian;
We have used trees as supports for barbed wire by wrapping it around
the tree. The tree just grew over it, healing itself as it grew around
it.
