Note that since latest cx_Oracle versions (6.x+ at least) there is support to read and write UDT (User Data Type) directly via cx_Oracle. Current parameter handling makes it difficult to pass such types via Django due parameter wrapping.
Practical usage of this scenario is to allow Oracle GIS backend to manipulate SDO_GEOMETRY objects directly without doing very slow WKT conversions.
