I think putting some work and thought into inheritance and making it work
right would make a lot of people very happy, and inheritance is one of the
major ideas behind OO in any context. Another thing to expand upon would
be using classes ("tables") as datatypes. I believe this is doesn't work
all that well. But we're surely "ORDBMS material", if you like.

Pure object-oriented databases (which is where the oid thing comes from)
are somewhat separate though, they represent a paradigm shift similar to
moving from, say, hierarchical or network databases to relational ones.
The research in that area is not at all complete and it lacks a
standardized query language and a whole bunch of other stuff. Since a
major goal of this project is moving ever closer to SQL compliance,
becoming an "OODB" is not in the near future.
