I've done only a little with Reticulum so far. Maybe we should aim to support LXMF rather than plain Reticulum (asynchronous, store-and-forward allows LXMF to work over intermittent networks).

Either way we just need to store a key and some way of flagging that its a Reticulum (or LXMF) address.

The #meshtastic people might want an option, too, but I know next to nothing about their work.
