Sounds like the biggest diff is that I use 'son' or 'sub' instead of 'daughter' -- shorter. :-)

I have a method that gives a short unique ID-string. Easier to read (a number might be confused with other data). You probably get a little more speed of using arrays and ints.

I only store sup and an array with subs in obj and use methods to find brothers. Fewer possible bugs to keep obj updated when deleting/adding/serializing/etc.

I have Links between objects in different parts of the tree (you don't need that, I'd guess). Would have been better to make objects out of Links but I have a small subapi to e.g. add link, del link and find links to/from obj.

In total, this was little code and never gave me any problem. If I should redo it I'd probably let the IDs be invisible in the api, just to be cleaner.
