Ultimately, it would be nice if all verifiable logs used each other's
gossip channels. For CT we are planning to at least gossip in TLS
Another obvious gossip channel is XMPP.
There's talk of using a verifiable log for the Tor Consensus. So I
guess there will be a Tor gossip channel.
And so on.
The interesting question is how all these mechanisms might coordinate.
