Can Oracle Heterogeneous Services be used to connect to a SQL Azure database? I would like to be able to use a database link from an Oracle 10g database to a SQL Azure database.

Will Oracle Heterogeneous Services support this?

I can see various articles relating to connecting to SQL Azure via ODBC, so does this mean that it will be possible to do it using Oracle HS, or am I oversimplifying things?
If there is an ODBC driver to connect to it, then the Oracle Transparent Gateway for ODBC should work just fine.
