Vista - Chaining WXF services

I would appreciate some architectural advice on chaining services.

As an example I have two discrete services hosted in a single Windows
service.
For most of the time these services are accessed by clients to provide non
related functionality but in one case service A needs to call service B in
order to fulfil a client request.

The obvious solution would be for service A to act as a standard client of
service B (Service Reference from Visual Studio etc) but this seems
inefficient as both services are hosted in the same process and establishing
a communications channel to effectively talk to yourself seems unnecessary.

Is there any way of services hosted in the same process chaining calls
without this overhead ?

Instance the class directly with new and call the service method.

look for generic approach in "Sharing an Instance"
