All the features (hacks?) in there have to be somehow available using fortress, merlin or whatever. We have another lifecycle type, the request lifecycle component. This is an extension to poolable and means that per request only one instance of this component is used. So if two other components lookup this request lifecycle component, they get the same instance. The implementation of this extension is a little bit difficult as we have sub requests that run in the same thread but have a different set of request lifecycle components. In addition it's possible to process on request multi threaded which makes this even more difficult. There are some other important extensions like the environment handling for the source resolver and the sitemap configurable components. They use more or less the same technique used for the request lifecycle components. I'm more and more thinking that we should do one thing after the other: first creating our blocks and than moving to fortress or merlin. Or the other way round, if someone things that it makes more sense. But we should avoid doing both at the same time. I mean, we are currently happy with ECM - it works, it's stable and the only real concern we have is the big cocoon.xconf which is solved with blocks anyway. (I don't want to say that fortress/merlin are not stable with this). Carsten
