Multiple Monero hosts 
Hello, i've a question with this.

- Support multi ports too, some host no use same port for example if you use three host and there host use different port is possible to connect.
- Possible Failover? what happen if you have 5 host and then three is down and later "main host" is back, it's connect again with the main or still using current host.
- Also what happen if host use rpc-login? and multi host use different logins.
