Thanks, Zulq. I also received a similar helpful tip from Ramon, and was 
surprised how easy it was to use several of those object-graph-aware 
streams, like ReferenceStream, SixxWriteStream, SixxReadStream. So that is 
what I will do for now.

Very sobering to think how many wrong direction I could chase without all 
the help from this group ...
