I have a Zope + DCOracle2 setup, and I was thinking of moving to Zope + eGenix ODBC (which will use unixODBC) however that still leaves me lacking a driver to connect this to the Oracle server.

There are a number of variously priced commercial drivers out there like EasySoft, Merant, OpenLink, etc.

Someone built upon a previous open source EasySoft driver: http://fndapl.fnal.gov/~dbox/oracle/odbc/

Anyone have any suggestions/experience?
