Thank you for this hint!

It works 95%. Since no REQUEST is given to __getitem__ I get
it like this: 

if hasattr(self, 'REQUEST'):
    request=self.REQUEST

This or something differnt seems to change the result
of getSecurityManager().getUser(): I always get the
anonymous user.

Does someone know why getUser() in __getitem__ is diffent than in
other methods?

The next thing is working, but it is not nice: the call to
__getitem__() returns the content of a file to the browser. But Zope
misses the docstring of the string. I solved by adding the content to
the request object and returning a function which returns this, but a
nicer solution would be better:

request._return_file=self.download(key, REQUEST=request)
def return_wrapper_with_docstring(REQUEST):
	"docstring"
	return REQUEST._return_file
return return_wrapper_with_docstring
