My personal opinion is that a generic tree algorithm is less useful  
than the generic relationship API that has been proposed and is
being worked on. There are four 'competing' implementations of this  
API, of which one (ally's hier module) is actually implemented
as a nested tree in the database (iirc). Your implementation could  
almost be considered the 5th, albeit lacking in flexibility.

Trees / Hierarchies are just one type of relationship, and I also  
think that caching / persisting trees is probably going to be more  
effective
for a lot of cases, but it will fall apart with _lots_ of data. I am  
not casting judgement on your code / plans, but I like how Vlado is
approaching the problem, and thus my support goes to him.
