I still don't see how this helps me.  It is closer, but doesn't solve
the fundamental problem of wanting to check the access control.  My
handler code for /admin would look something like this:

def handler(req):
  print "Hello world"

  # I can't see how to do the next two lines which could have
  # different permissions
  ... check credentials in req against "/api/object/list"
  ... check credentials in req against "/api/object3/delete"

  # The next two could be done by calling the code that
  # implements /api directly (or playing with internal_redirect)
  items=request("/api/object/list")
  request("/api/%s/delete" % (items[3],))

  print "more output saying item3 was deleted"
