Unfortunately, many sites block Tor relay IPs regardless of their exit
policy. So, if you share one IP between the relay and other services,
your might be impacted. This is especially true for exit relays.

The offer is well appreciated. In the current design, directory
authorities and bandwidth authorities play a very special role. There
are several ideas on how to improve the situation and then open
participation to the broader community, but for the time being,
authorities can only be run by people very close to the core dev team.
