[Zope] Zope using ODBC on Linux question

Hi list, After searching everywhere I know of, I've found that my only options for getting Zope to talk ODBC on Linux are: 1) pay for egenix's Zope ODBC Database Adapter product 2) try your luck retrofitting ZODBCDA (last hacked for unixODBC in 2001, and doesn't seem to build on Zope 2.6.2 with python 2.2) This is a sort of tragedy for me, after getting unixODBC and freeTDS configured properly (I can talk to SQL Server from Linux!!!), and now I have to go buy a non-free product for Zope :( It's not giving up the free-as-in-free-beer part, as $95 means nothing to the overall budget of this project; but it's losing the free-as-in-free-speech aspect that bothers me. Is there a free project out there that I don't know about? -- mitchy
