Failover to additional server based on a lookup

Feature Suggestion.

Since some of our people are in security sensitive context, in the event their audio server is blocked, it would be nice to have a way to lookup the new server/ip address.

E.g. have a field that says check server update at: IP.ADDRESS.GOES.HERE

then periodically or in the event when audio file is not found, goes to this address to see if the server address has been changed. if so, update the ip address on the Source.

Not sure if this is what current audio source does, does it automatically fails over from one server to another?
