How does gift wrapping address what GP brought up? I read through and AFAICT it obscures explicit metadata in the message, but not external stuff such as source/dest ip that logging any shared relay could give you.
AFAIK the only real ways to get metadata privacy are onion routing (increase the chance of a non-compromised node) and N-anonymity (decrease the value of a discovered connection).
