WCF - passing the current pointer in the header

Question

I have a WCF service that needs to know the Principal of the caller.

In the service constructor, I:

Principal = OperationContext.Current.IncomingMessageHeaders.GetHeader<MyPrincipal>("myPrincipal", "ns");

and in the calling code there is something like:

        using (var factory = new ChannelFactory<IMyService>(localBinding, endpoint))
        {
            var proxy = factory.CreateChannel();
            using (var scope = new OperationContextScope((IContextChannel)proxy))
            {
                var customHeader = MessageHeader.CreateHeader("myPrincipal", "ns", Thread.CurrentPrincipal);
                OperationContext.Current.OutgoingMessageHeaders.Add(customHeader);

                newList = proxy.CreateList();
            }
        }

All of this works great.

My question is: how can I avoid wrapping all proxy method calls in using (var scope...{ [create header and add to OperationContext]?

Can I create my own ChannelFactory that will handle adding the myPrincipal header to the operation context? Something like this will save the entire copy / paste load, which I would rather not do, but I'm not sure how to achieve it :)

thank
