But I have to convince my boss... How meny ours do you think it wood take to get DCom to work in Wine? 50 h / 100h / 500h / 1000h ?
Good question. I'm afraid I have no idea, it's impossible to predict.
Maybe it helps, if you have a OPC server source code to see what is needed on COM/DCOM functions. You can find a free (LGPL) OPC server on the following link:

We are a small software company, and I know that some customers of us are interested in OPC on Linux in the past. There is one working solution as far as I know. It is a OPC Toolkit from Technotrend which is based on the COM/DCOM implementation EntireX of Software AG. But its not Open Source unfortunally.
Some links about this:

I don't know the license cost of this products at the moment, because our customers decided not to use Linux.
