Bitchat does work with Meshtastic as of the most recent release. It also lets you self host a relay, because it uses Nostr relays. I'm not so sure about white/black listing so yours DOES get used, but you can absolutely host one. Routing through the Internet is something both Bitchat and Briar support, Briar through tor, Bitchat through Nostr (optionally also through tor). Disabling Internet routing at this time may require turning off Internet for Bitchat -- haven't dug on that one.

I do like the store and forward idea, though a thought on that is that while it makes sense for DM's, it makes less sense for group chats, which, being real time, make the shelf life of messages a bit short. It makes good sense for forum like content though. I think so far Bitchat has treated this as a bit out of scope, at least at this stage of development, and it is a reason that indeed, Briar is still quite relevant.

Bitchat only just recently even added ad hoc wifi support, so it's still very early days.
