While I've needed access to such a fp object, it's been limited 
to cases where I passed a file-like object to the constructor 
instead of a path-name:

   tf = tarfile.open(fileobj=foo, ...)

so I had access to "foo" without reaching into the 
tarfile/zipfile object for the internal fp.  Usually this 
involves using a StringIO object or a temp-file that then gets 
cleaned up when complete.
