Enables use of Spring's RMI remoting extension points to propagate the `ContextHolder` (which should contain an `Authentication` request token) from one JVM to the remote JVM.

The beans are wired as follows:

`<bean id="test" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
<property name="serviceUrl"><value>rmi://localhost/Test</value></property>
<property name="serviceInterface"><value>test.TargetInterface</value></property>
<property name="refreshStubOnConnectFailure"><value>true</value></property>
<property name="remoteInvocationFactory"><ref bean="remoteInvocationFactory"/></property>
</bean>
<bean id="remoteInvocationFactory" class="net.sf.acegisecurity.ui.rmi.ContextPropagatingRemoteInvocationFactory"/>
