+ - Pairing works like this:
+ -
+ - * The user optns StartPairR, which prompts them for a secret.
+ - * The user submits it. A PairReq is broadcast out. The secret is
+ -   stashed away in a list of known pairing secrets.
+ - * On another device, it's received, and that causes its webapp to 
+ -   display an Alert.
+ - * The user there clicks the button, which opens FinishPairR,
+ -   which prompts them for the same secret.
+ - * The secret is used to verify the PairReq. If it checks out,
+ -   a PairAck is sent, and the other device adds the ssh key from the
+ -   PairReq. An Alert is displayed noting that the pairing has been set up.
+ - * The PairAck is received back at the device that started the process.
+ -   It's verified using the stored secret. The ssh key from the PairAck
+ -   is added. An Alert is displayed noting that the pairing has been set
+ -   up. Note that multiple other devices could also send PairAcks, and
+ -   as long as they're valid, all those devices are paired with.
