After three specialized meetings on Be stars, it: appears that the Be phenomenon is more complicated than we have thought. Five fundamentally different models are now competing. All five are actually based on an assumption that the Be stars are only a specialized (perhaps more easily noticeable) case of a more general phenomenon. Carefully arranged observations may decide between competing concepts, for example between spheroidal and disk-shaped circumstellar envelopes, and they can decide on the location of the cool strata (emitting Balmer lines) and hot strata (N V, C IV, Si IV). Eclipsing interacting binaries provide valuable clues.
