I guess would there be a good object-oriented database engine, people
woul've been using it already :-(((

... which, again, reminds me of the way I do it: I have
transaction-oriented protocol adapters on top of stream-oriented. Just
today was solving a problem - how to support the streaming request (in
my particular case, it's backup or restore) over such architecture
without penetrating the transaction/stream border. And getting back to
the topic, 'implements java.io.Serializable', huh? Do you use/plan
CORBA? RMI? Does anyone have a first-hand experience with comparing
those two?

Related question (off the top of my head, so that's just a thought
aloud): is Java serialized stream documented? (guess so) What is a cost
of cross-platform (mean cross-language and big/little endian (or it's
always network order?)) serialization engine? (guess VERY HIGH)
