Good point, but ordinarily one mixes RackMountable with another Zope class such as SimpleItem.Item, or uses it as part of a ZClass. In either case, Acquisition gets added in. SimpleItem.Item only subclasses ExtensionClass.Base, and I got an AttributeError on __of__ unless my RackMountable subclasses Acquisition.Implicit also. bizarre isn't it?

I'm not actually real fond of the DDO term, because "Dynamic Data Object" doesn't quite do justice to what these things actually are. I am definitely open to suggestions for a better name. (Facade? PlaceHolder? InsideOutObject? ExternalDataObject? BrainInjectedObject?) what about "penguin" ? :-)

Also, while I'm babbling about versions, it's important to note at this point that ZPatterns versions below 1.0.0 should be considered subject to change even with respect to developer-level API's. They get more stable as the number gets higher, which is why LoginManager changed a lot less between 0.8.0 and 0.8.5 than half as much as ZPatterns changed between 0.2.0 and 0.3.0. The change to 0.4.0 will probably be another big jump, due to the DDO stuff as well as the Indexes stuff. Predicates may even make it in, in some small way. Have you got an idea of when 0.4.0 will ship ?
