It's now possible to add an LXMF contact address to interface discovery data, using the `discovery_lxmf_address` option per interface. The intention of this is to make it easier for operators to get in contact with each other, coordinate network interconnections and local network expansion, or just get in touch with other local operators.

Would be good to have support for this field added to user-facing applications as well - still need to integrate it in Sideband myself ;) But at least, you *can* see it in the `rnstatus -D` output.

This is useful! What do you think about also having a field to announce a NomadNet page for the interface? I’ve been wanting a way to include a status or info page so that users can check on the interface’s health or, for public interfaces, get more information to decide whether it’s relevant and useful for them before connecting.

That's not a bad idea @K8. And it's only 16 bytes, plus a few bytes of packing overhead, so should be well within what we can squeeze into an announce.

An additional global setting for `discovery_lxmf_address` (and nomadnet address as K8 suggested) for all public interfaces in your config would be a nice quality of life thing.
