You may want to look at the new Persistent Object Mapping Tool from 
Enfin. It will support polymorphic instances in the way you describe.  Of 
course if you have a RDB setup with a single column that is the foreign 
key to one of many tables, each key needs to be unique amongst all the 
tables.  If you don't meet this requirement, then it would be necessary 
to write a line or two of code.
