Awesome, would love to see some more real-world usage!

1. Yep, it even has a configurable exponential backoff. But you do need to handle retries, if a command times out for example.
2. I think so, It works well running against my testnet which has a custom chain id and address prefix.
3. Yep, check the ./dist/ folder in the github repo
4. I'm testing against node 7 and 8, will probably work with 6 as well.
