Hi Eike,
For the CDO Teneo integration, I can just work with the standalone cdo version probably, correct?

I remember that you posted some code for standalone cdo somewhere, can you repost it for me?

Thanks!

Yes, I'd choose the easiest setup: client and server in one vm, start
with a MEMStore and look at its implementation.

I think you mean the one I gave Stefan. It's also in CVS:
