Sorry I missed this post.
I have a version for Oracle that works well enough to use, but everytime I look at it I think it's the wrong approach. If acs_attributes/acs_object_types where acs_objects and acs_attribute.new created the database columes then the TCL api becomes: package_instantiate_object. Either way acs_attribute.new needs to create the columns, the only real issue would be that the acs_object_types table would need an acs_object_type_id column.
I'll gather the code up and post it somewhere. The one issue with acs_attribute creating tables is in Oracle you have to grant create table role to the user id.
