Yes, I've actually missed that.
I suppose I was looking for a file_streaming implementation.
I think ExternalFile could benefit from implementing it.

I'm actually contemplating fixing it, although I'm not so pleased
with the user interface of ExternalFile and I would like to
limit the access to just a few directories on the file system
from the Zope Configuration preferably. I might rewrite the complete 
product.
