Let your brains classes __init__ take a REQUEST parameter. They can extract the properties it needs, before calling the base class __init__.

Note also that your brains class can acquire REQUEST using self.REQUEST.

Normally thats true, however we need these parameters in a __init__, and constructors run with an empty acquisition context.

Actually, this will work because the LocalFS object is calling the constructor so I can acquire REQUEST from the LocalFS object's context. This sounds like a great idea. I'm going to give it a try. Thanks! Actually, I don't need REQUEST at all, though because I can define a 'brain' class to have a standard constructor then return the actual object through, say, the __call__ method. --jfarr
