If my understanding of their literature is correct, the latest version
of Vbase (called OB2?) has C++ as its host language.  All interaction
is done through member functions.

This exists to some extent in HP's Iris and in MCC's ORION.  I guess an 
OODBMS that supports both features will be novel, but I don't know that 
Object-Sciences will be the first to do it.
