not rewriting next-hop, pointing default, ...s

If they buy transit, or do not buy transit from UUNet makes no difference.
You don't see a problem with pointing default at UUNet or any other
provider? This trace was to a network that did not exist, so it should not
have been sent to UUNet.

Hum. network that did not exist.....

Interesting concept.

can you ensure that the prefix was
not seen inside the UUnet AS bound?
