I'm not saying it will help, but it's more than registry access. It won't help you if you have 32-bit server, and 64-bit client. Or did you verify that it works for out-of-proc case already in wine?
Well, we have the sample attached here, and I got it to work using the x64 client and the 32bit COMServer.exe. Isn't that enough?
