Enough mind games. You have to pass the wires anyway, encrypt and trust

Which, generally speaking, will still not defeat traffic analysis without special considerations...

I'm gonna go ahead and suggest trickle connections. It's in my paper about mesh networking that I might release once. You have n connections to n nodes (1 on 1) and you continuously flow (both directions) random data over it. Occasionally instead of random data you put an encrypted package in it. The other end continuously (tries to) decrypt packages. This way you never know if something is being sent or not, at the cost of some bandwidth. Schematically: generate random > send buffer secret package > send buffer send buffer > stream encryption > transmit buffer transmit buffer > rate limited connection to peer on the other side: receive buffer > stream decryption > package detector > usual way of dealing with incoming packages. If you never actually use these trickle connections, but you do have them, you can deny being the origin of packages (I didn't know what it was! I got it over a trickle connection!). If you mark packages as "top secret" they should only be send over trickles and they'll never be network observable at all. Additional tricks such as delayed further transmission, network path mixing, etc. are all possible with what I have in my paper and should be (easily) doable in Tor. I never really understood the problem with traffic analysis.
