> Please, there is no 'free write back to tree' stuff ... then i haven't been able to get reasonable image of proposals from your summary.
and frankly from both answers i feel you both haven't been able to understand each other yet. maybe it would be better idea to setup wiki page where each of you could write how your proposal work in more algorithmic way, unify what the words like bundling/reversibility means and only after that make some comparison of pros x cons. i'm myself lost from your posts now, sorry. pavel
