arcobjects - OGIS Ole Db provider sample with read/write capability

I'm trying to determine what level of effort would be required to develop an OGIS Ole db provider for ArcGIS.

There is a sample that is read-only. I would like to be able to edit featureclasses in the ole db workspace using the out-of-the-box editing tools in ArcMap. Plus, I would prefer to develop in C# instead of C++.

I see that there was an effort to do this with zigGIS, but it never was completed.

Does anyone know of sample code showing how to do this?
