[Operators] transitive federations?

Out of curiosity, do you have a specific need for relaying or "transitive federations"?

In general, if domain A is openly federated, it should be able to communicate directly with other domains such as B, C, D, E, ... without prior administrative configuration.

To maximize the likelihood that other domains will communicate directly with domain A, A may want to follow a few best practices, such as:
* have DNS SRV records,
* enable encryption,
* have TLS/SSL certs for each server issued from a recognized CA, and
* have TLSA (DANE) records in a DNSSEC-secured zone.  (in case other domain operators choose to not trust your selected CA but may instead trust DANE for cert validation...)

Anyone else have tips?
