I'm not aware of any native driver that does support this, except a
You can also use mxODBC with an XA enabled ODBC driver (I think
the EasySoft Oracle ODBC driver is capable of doing XA), but the
APIs for setting this up are different for each driver.

I'm not sure I can follow you here: if you do two-phase commit
under the control of a transaction manager such as MQSeries
or MS DTS, then the transaction manager will take care of
the transaction, not the database interface (see e.g. the DCOracle2
XA example in http://pymqi.sourceforge.net/).
