i think inheritance will work for both session beans and interfaces. as far as i know, you just have to make sure to annotate the sub-interface with @Remote/@Local even if the super-interface has it. ditto with the session beans, except using @Stateless/@Stateful. you should put together a quick test though to make sure it will suit your needs.
