Robert, maybe you're interested to participate in this conversation:
https://groups.google.com/d/msg/twister-users/cgxyB2oOQkk/Ov-MUUv3uG4J
Also about the secret, it allows you to put a static address somewhere
and receive anonymous payments. It doesn't preclude treating the address
itself like a secret though and sending that over a special channel like
Twister uniquely to different participants. You don't have to send
everyone the same address.
Together with those 3 schemes 1) Twister transmission 2) Stealth
addresses 3) CoinJoin, we have very strong financial privacy.
Are you on IRC ever? I'm in Freenode #darkwallet. I've got some
questions if you're around in next few days for some minutes.
