Well, Scott's hierarchy wasn't complex so I'm sure that won't be an issue...
I have found the easiest way to uniquely identify taxonomy nodes is with a hash that is the concatenation of the node's parent with that of the node's sequence.
...but you still have a potential collision issue here. You're adding a lot of complexity and potential for error to an otherwise very simple problem.
I totally agree with you that in the complex case, you may well need a more performant solution that UUID and the trade off of the extra code involved may well be worth it. But in the case at hand, I think your solution is overkill.
