XA Transactions / Sending raw TDS packets through ODBC

Hello,

I'm trying to implement XA transaction support for pyodbc and have got 
quite a long way by using the XA helper stored procedures in the dll 
supplied with the microsoft jdbc driver. Unfortunately, though I can 
successfully control the XA transactions through the stored procedures I 
am unable to enlist a connection into a transaction with the returned 
cookie. It does seem though that jtds has code to do this from java.

So my question is, how can I send a raw TDS packet through the ODBC 
interface? It seems the packets are very simple[1].
