It's definitely worth looking hard into this before doing it IMO. Depending on the
nature of your
application there are performance implications in going down an OR route.
Scott Ambler's papers are a good starting read. But it's worth having at least a
cursory glance
at CORBA persistence, 'en

SOAP is relatively costly (at the moment) in terms of 2) data size. A binary protocol
