You'll probably have to end up doing this yourself, but maybe one of 
these would work:

http://zope.org/Members/TheJester/PortableHole
http://zope.org/Members/andym/Rewriter
http://zope.org/Members/astaubo/Redirector

At least they can give you a pointer on how to do the sort of proxying 
you want. I never was able to get Rewriter or Redirector to work (which 
is why I wrote the v. simple MovedObject) but maybe you'll have better luck.

If you do it yourself, you will probably make A an instance of your own 
product which extends folder but over-writes the appropriate methods 
(traversal and call and whatnot) to make something called on it actually 
use its contents.

I have to say, naturally, that this seems like a very strange thing to 
do, and I half suspect that there's a different design that will make 
things easier. But I'm sure you have your reasons.
