**What it demonstrates:** A new DHT is created by the Go program `dht-interop`. In a separate terminal or machine, a Node.js program connects to this DHT. One connected, each verifies that it can find the other's content via the DHT.
`-b` means bootstrap mode. In this example, the go program is always the bootstrap node, so `-b` is always required.
Note that the node ID of `dht-interop` is always `Qm...6aJ9oRuEzWa` because it is being read in from `../util/private_key.bin` (a private key marshalled to X.509 generated by `util/private-key-gen`). This is to keep the peer id of the bootstrap server stable across invocations.
**Second terminal:** run the command printed out by dht-interop, replacing 127.0.0.1 with the IP of the server where dht-interop is listening. Example:
**What it demonstrates**: Two Go nodes are created and run a chat server using a shared PubSub topic. **TODO**: Should be a Go node and a JS node, once I get the two Go nodes version working.
