QuestionSuggestions on OLE DB architecture [modified] Pin

Hi all,
I'm embarking on a fairly complex project (I know. Please don't say simply "Google for it". I already did).

What I want is to implement an OLE DB layer between a physical DB (connection via standard OLE DB interface) and a client application.
The aim is to implement row level security and additional functions (such as logging) in the OLE DB layer.

So the architecture should be like this (top-down):

Client Application        <- Ole DB consumer application (MFC, .NET, Excel...)<br />
-----------------------<br />
OLE DB Provider           <- On the client. Dumb connection to my service via the Network layer<br />
-----------------------<br />
<br />
Network layer <- I really don't know how to pass through this<br />
<br />
-----------------------<br />
OLE DB Consumer/Provider service                  <- This should be on a network server. Here I'm implementing row level security. This service acts as an OLE DB consumer for the DB and exposes data to the client.<br />
-----------------------<br />
Physical DB               <- Any OLE DB-compliant database (mainly SQL Server or Oracle)<br />
-----------------------


My question is: what is the best way to implement the Network layer?

I found an OLE DB Remoting Provider by Microsoft, but seems outdated and not supported ATM. If using this, I should implement OLE DB Provider interfaces into the Service on the server.

Any suggestions?

(Cross-posted in the C++/MFC Forum. Don't know which forum is best suited)
