Well, not quite.  Plane mirrors do.  And, even then, there's a small
delay for the light to get from you to the mirror and back, so when
you see your image in the mirror, you're no longer what you're seeing
there :-)  This wouldn't be that different :-)

No dispute here.  But if it could, later on, realize that the package
was signed and use http interval fetch tricks to obtain only the
signature, it would be way cool.

Which would be a good reason for the key bearers :-) to actually sign
packages that go to rawhide more often.
