code to create an Action<T> that will call a method that takes an object.

test.cs

	sbc.Subscribe(subs =>
					{
					    Type type = GetRuntimeType(); // e.g. reflecting IHandle type...

					    //get pointer to generic method of specific type parameter
					    var methodInfo = subs.GetType().GetMethod("Handler", BindingFlags.Instance | BindingFlags.Public);
					    methodInfo = methodInfo.MakeGenericMethod(type);

					    // set up an action compatible with our method
					    // object is in commmon with any type we find above, so this will work
					    Action<object> a = m => serviceBus.Publish(m);

					    // following call to invoke is equivalent to:
					    // sbc.Handler<T>(m => serviceBus.Publish(m));
					    methodInfo.Invoke(subs, new object[] {a});
					});
