I think this is not was Steve was saying. Of course, the DOM nodes will be
stored independently as OzoneObjects. The problem may be the overhead of the
database when storing small objects (like DOM nodes). To avoid this I was
thinking about clustering of nodes. Actually, Steve do not want such tricky
things. He want each node to be stored as an independent database object. So,
you are of the same opinion. Right?

Thanks for this link. I will check it out.

So far not that noisy like the Cocoon list - but we are coming ;)
