Don,
does your approach handle directed graphs ( DAG ) ?
Actually our module is just a result of our research for new
data type which could handle DAGs ( yahoo, dmoz -like hierarchies)
effectively in PostgreSQL.
While we didn't find a solution we decided to release this module
because 64 children would quite ok for many people.
Of course, 128 would be better :-)
How about 'move' operation in your approach ?
Regards,
Oleg
