Yeah Michael Jackson was ahead of his time with sleeping in one of those.

Another idea to prevent peeking the nitesend transactions would be using encrypted communication. In this case, we could use for example hyperboria (cjdns) technology; combined with sync, that would mean all sync coins would have an own ipv6 address and an encrypted communication link! Nitesend transaction could be collected by sending the offers throught these kind of links, securing them from all peekers. Actually, the whole comunication between peers could be done throught private hyperboria network. I guess it would be better than TOR and vpn together.
