The current code does not work properly (at least for our early tests)
but I could share it if you want to try it yourself.

I don't know exactly what GDL2 does. But I think that the code is
working fine on Linux, with the GNU Foundation framework. On Panther
some of the methods defined in EOFault have been moved to NSObject and
this cause some conflicts. At least this was Mirko's diagnosis.

Is it open source, or is just available to registered customers?

I am looking for a production grade EOAdaptor, in order to try to
start coding an Oracle adaptor on my own.

In the next days I will try to follow all you suggestions to move our
code to Tiger + XCode.


Thanks again for all your suggestions.
