ChannelProxies can be intercepted now:

[ServiceContract]
public interface IFooService
{
    [OperationContract]
    void Foodo();
}

ActionInterceptor interceptor = new ActionInterceptor( invocation => Console.WriteLine("Executing {0}.", invocation.Request.Method) );

kernel.Bind() .ToMethod(context => ChannelFactory.CreateChannel(new NetTcpBinding(), new EndpointAddress("net.tcp://localhost/FooService"))) .Intercept() .With(interceptor);
